Candidates describe Brady's Software Engineer work as designing, building and maintaining applications that support its products and its manufacturing and operational processes, working beside product management, QA and operations colleagues. Writing technical documentation, reviewing code and testing are part of the job. That breadth explains why the reported questions cover the whole engineering cycle instead of one specialty: the software development lifecycle, web services, code quality, debugging and everyday coding.
The requirements candidates list name Java, C# or Python, experience with Agile or Scrum, and a grounding in software architecture and design principles. Familiarity with AWS or Azure, DevOps practices and database management and optimization appear as extras. You do not need every item, but your project stories should show which ones you have really used and how deeply, and you should be honest about the rest.
The reported coding prompts are fundamentals: reverse a string, state the time complexity, handle edge cases, and discuss a data structure you know well. The challenge is precision rather than novelty. Write correct code in your best language, state its complexity unprompted, and list the edge cases yourself: empty input, a single character, null, and characters that take more than one code unit.
Candidates also describe three evaluation areas, technical proficiency, problem-solving and communication, and a loop that feels friendly in tone. Give the behavioral questions the same weight as the technical ones. Conflict, prioritization under deadlines, learning quickly, contributing to a team and motivation each need a real story from your own work, told in the first person, with a result.
Phone Screening
reportedCandidates describe this as an initial call about your background and how well you fit the role. Because it centres on your own experience, the preparation is a clear, specific account of what you have built, which of Java, C# or Python you have worked in, and why this role and this company interest you.
What to demonstrate
- Your background and relevant experience, as the stage is described
- Fit with the Software Engineer role
- How clearly you explain your own work in a spoken conversation
How to prepare
- Choose two or three projects and write down for each what it did, your part in it, the language and tools, and one result you can describe honestly.
- Match your experience against the requirements candidates list (Java, C# or Python; Agile or Scrum; architecture and design principles) and note where you have a direct example.
- Rehearse the motivation and learning-a-new-technology stories aloud so they sound like conversation rather than recitation.
- Write a short answer to why Brady and this role, after reading what Brady itself publishes about its products.
In-Person Interviews
reportedCandidates report in-person interviews with a mix of people, including hiring managers and team members. A mixed audience means one project may need a technical telling for engineers and a plain-language telling for a manager. Candidates do not say which questions come at this stage, so keep the technical, problem-solving, coding and behavioral sets all ready.
What to demonstrate
- Fit with the hiring managers and team members you meet
- How you communicate with different kinds of stakeholders
- Technical and problem-solving ability when discussed face to face
How to prepare
- Prepare a technical and a plain-language version of your strongest project, naming your specific contribution in each.
- Keep the full set of reported questions in rotation, since candidates do not tie them to stages: lifecycle and web services, code quality and debugging, a short coding exercise, and behavioral stories.
- Practise writing a short function in a plain editor or on paper while saying its complexity and edge cases aloud.
- Prepare questions for hiring managers and team members about how engineers work with product management, QA and operations, and how code review and testing are handled.
PracHub editorial advice for the preparation topics above.
Reciting the software development lifecycle as a textbook list of phases with no link to a project you worked on.
Walk through the lifecycle using one of your own projects: how requirements arrived, how work was split in Agile or Scrum, where code review and testing sat, and how releases and maintenance were handled.
Answering the RESTful versus SOAP question with "REST is newer and simpler" and nothing else.
Compare them on contract (OpenAPI versus WSDL), message format (JSON or XML versus the SOAP envelope), statelessness and caching, security (HTTPS and tokens versus WS-Security) and tooling, then say when you would still choose SOAP.
Writing the string-reversal function quickly, stopping at the happy path, and never stating complexity or edge cases.
State O(n) time and the space cost of each approach, then test empty input, one character, null, whitespace and characters that use two code units (emoji, combining marks) before you call it done.
Telling behavioral stories entirely in the plural, so your own contribution disappears, or casting a teammate as the villain in the conflict story.
Structure each story as situation, your action, result. Describe the other person's reasoning fairly and end with what changed because of what you did.
Answering the debugging and solution-evaluation questions with intuition instead of a sequence.
Rehearse a fixed order: reproduce, narrow the scope, check recent changes and logs, form a hypothesis, bisect, fix, add a regression test. For evaluating options, name your criteria, a prototype or spike, and how reversible each choice is.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.
Write a function to reverse a string in your preferred programming language.
Write a function to reverse a string in your preferred programming language.
Approach
- Clarify first: is the input possibly null or empty, and should reversal work on characters, Unicode code points or user-visible characters (grapheme clusters)?
- Give the idiomatic answer for your language: in Python s[::-1]; in Java new StringBuilder(s).reverse().toString(), which keeps surrogate pairs together; in C#, ToCharArray(), Array.Reverse, then new string(chars).
- Then write it by hand with two pointers: convert to a char array, swap index i with n-1-i while i < j. That is O(n) time and O(1) extra space beyond the array, which is itself O(n) because strings are immutable in all three languages.
- Call out the traps: repeated string concatenation in a loop in Java or C# is O(n^2) because each step copies the string, and a recursive version uses O(n) stack depth, which overflows on long input (Python's default recursion limit is 1000).
- Name the Unicode edge case: reversing code points breaks combining accents and emoji sequences; reversing text elements (StringInfo in .NET, the third-party regex module's \X in Python) keeps them intact.
Follow-up
- How would you reverse the order of words in a sentence instead of the characters?
- How would you check whether a string is a palindrome, ignoring case and punctuation?
- How would you reverse a string in place if you were given a mutable char array?
Explain the time complexity of your solution.
Explain the time complexity of your solution.
Approach
- Define n explicitly (string length, array size, number of nodes) and count the dominant operation as a function of it, dropping constants and lower-order terms.
- Give time and space separately, and include the hidden space: a new output string, auxiliary arrays, and recursion stack depth.
- Distinguish cases: best, average and worst case (hash map lookup is O(1) on average but O(n) worst case with heavy collisions), and amortized cost (appending to a dynamic array is amortized O(1) because doubling makes resizes rare).
- Spot hidden costs in library calls: Python slicing copies O(k) elements, list membership with
inis O(n), sorting is O(n log n), and string concatenation in a loop can turn O(n) into O(n^2). - State whether the bound is optimal: for string reversal you must touch every character, so O(n) time cannot be beaten.
Follow-up
- Why is appending to a dynamic array amortized O(1) when a single resize is O(n)?
- What is the space complexity of a recursive solution to the same problem?
- When would an O(n log n) algorithm beat an O(n) one in practice?
How would you handle edge cases in your code?
How would you handle edge cases in your code?
Approach
- Enumerate edge cases by category before coding: empty or null input, a single element, duplicates, already sorted or reverse sorted input, boundary values (0, negative numbers, maximum integer), very large input and non-ASCII text.
- Decide a policy for invalid input and state it: validate with guard clauses and throw (ValueError in Python, IllegalArgumentException in Java, ArgumentNullException in C#), or return a defined default, and keep the choice consistent across the API.
- Watch numeric boundaries: Java and C# int arithmetic overflows silently by default, so compute a midpoint as lo + (hi - lo) / 2 rather than (lo + hi) / 2; Python ints do not overflow.
- Prove the handling with tests: parameterized tests (pytest.mark.parametrize, JUnit @ParameterizedTest, xUnit [Theory]) for each listed case, and property-based tests (Hypothesis, jqwik) for invariants such as reverse(reverse(s)) == s.
- Trace one edge case through your code out loud after writing it, rather than claiming it works.
Follow-up
- Should a function return null, an empty result, or throw on bad input? When would you choose each?
- How do property-based tests find edge cases you did not think of?
- Which edge cases matter when the input comes from an external system rather than your own code?
Discuss a data structure you have used extensively and its benefits.
Discuss a data structure you have used extensively and its benefits.
Approach
- Choose one structure you have really used, for example a hash map, and name the concrete problem it solved: deduplication, caching lookups, counting occurrences or indexing records by key.
- Give its costs accurately: average O(1) insert and lookup, O(n) worst case under heavy collisions, amortized resizing when the load factor is exceeded (0.75 by default in Java's HashMap). Since Java 8, a crowded bucket turns into a tree, so lookup there is O(log n).
- Explain the implementation choice: Java's HashMap uses separate chaining, Python's dict uses open addressing; keys must have consistent equals and hashCode (or eq and hash), and mutating a key after insertion loses the entry.
- Compare with alternatives you would choose instead: TreeMap or SortedDictionary for ordered keys at O(log n), LinkedHashMap for insertion or access order, an array when keys are small dense integers. Python dicts keep insertion order from 3.7.
- Cover concurrency: plain HashMap and Dictionary are not thread-safe; use ConcurrentHashMap in Java or ConcurrentDictionary in C# when several threads write.
Follow-up
- How would you implement an LRU cache with O(1) get and put?
- How do chaining and open addressing handle collisions differently?
- When would a hash map be the wrong choice?
Keep soft-deleted accounts from blocking re-registration
app_user holds user_id, tenant_id, email CITEXT, password_hash (NULL for SSO principals), email_verified_at, auth_version, status ('invited','active','suspended','deactivated'), created_at, updated_at, deleted_at. Two live accounts for one address inside a tenant must be impossible, but an address freed by a soft delete must be reusable, and the same tenant may delete and re-register it repeatedly. Write the uniqueness DDL for PostgreSQL 16, then the equivalent for MySQL 8 where partial indexes do not exist, and say what each permits once three deleted rows already hold that address.
Approach
- Start from what is actually unique: not (tenant_id, email), but (tenant_id, email) among live rows. PostgreSQL says that directly — CREATE UNIQUE INDEX app_user_live_email ON app_user (tenant_id, email) WHERE deleted_at IS NULL. A full constraint over the same two columns burns the address permanently the first time someone deletes an account.
- Keep case-insensitivity in the type or the index, never in the application: CITEXT as given, or UNIQUE (tenant_id, lower(email)) as an expression index where the extension is unavailable. A case-sensitive unique column is exactly how two accounts for one human appear.
- For MySQL 8 the predicate has to move inside the key: add a discriminator column that is a constant 0 while the row is live and is set to user_id on delete, with UNIQUE (tenant_id, email, deleted_marker). Live rows share the constant and still collide; deleted rows differ from each other and stop colliding.
- State the NULL variant and its dependency: leaving the marker NULL for deleted rows also works, because a unique index treats NULLs as distinct — true in MySQL, and true in PostgreSQL only under the default NULLS DISTINCT, which PostgreSQL 15 lets you reverse. Check the polarity against the three existing deleted rows: constant-on-live is what preserves the collision you want, and reversing it silently admits duplicate live accounts.
Follow-up
- A deleted account re-registers with the same address the next day. Do the old resource rows follow the new user_id, and how does the API keep the two principals apart?
- How do you honour an erasure request while resource_revision.actor_user_id still references this table?
Write the update path that detects a concurrent edit
resource carries version INT NOT NULL DEFAULT 1. resource_revision holds revision_id, resource_id, version, actor_user_id, change_kind, patch JSONB, request_id, created_at with UNIQUE (resource_id, version). outbox_event holds aggregate_type, aggregate_id, aggregate_version, event_type, payload, status. A PUT carries the version the client read. Write the exact statements for the single transaction that applies the edit, records the revision and enqueues 'resource.updated', and give the handler's branch on zero affected rows. Then say what PostgreSQL 16 does under READ COMMITTED when two of these updates hit one row at once.
Approach
- One transaction, three writes, no network call inside it: UPDATE resource SET title = $3, version = version + 1, updated_at = now() WHERE resource_id = $1 AND tenant_id = $4 AND version = $2; then INSERT the resource_revision row at version $2 + 1; then INSERT the outbox_event row at the same aggregate_version. The event goes to a table rather than a broker because no transaction spans both.
- Branch on the affected-row count before doing anything else. Zero has three causes — stale version, wrong tenant, row gone — so re-read once and map to 409 carrying the current version, or 404 for an id outside the caller's tenant, which also stops the endpoint confirming that another tenant's id exists.
- State the engine behaviour instead of assuming it. Under READ COMMITTED the second UPDATE blocks on the row lock, and when the first commits PostgreSQL re-evaluates the WHERE clause against the newly committed row, so the version predicate now fails and the statement reports zero rows. Under REPEATABLE READ the identical collision raises SQLSTATE 40001 instead, so the handler must fold both shapes into one conflict response.
- Keep UNIQUE (resource_id, version) even though the predicate already serialises writers. It is what makes a lost update unwritable if any other path ever reaches the revision table, and it converts a logic bug into 23505 rather than into a silently missing history row.
Follow-up
- A client sends the version it read ten minutes ago and the resource has moved three versions. What is in your 409 so it can resolve the conflict without a full re-fetch?
- Two editors, two disjoint fields, no overlap. Does your answer still refuse the second write, and should it?
Explain the software development lifecycle.
Explain the software development lifecycle.
Approach
- Name the phases in order and what each produces: requirements (user stories or a spec), design (architecture and interface decisions), implementation (code plus unit tests), testing (integration, system and acceptance), deployment (a release), and maintenance (bug fixes, patches, enhancements).
- Contrast the delivery models: waterfall runs each phase once in sequence and suits fixed, well-understood requirements; iterative and Agile models such as Scrum repeat the whole cycle in short sprints, so working software and feedback arrive early.
- Explain why the model matters: a requirements defect found in production costs far more to fix than one caught in review, so iterative models and early testing shorten the gap between a mistake and its discovery.
- Tie it to modern practice: continuous integration runs the build and tests on every merge, and continuous delivery keeps the main branch releasable, which shrinks the test and deploy phases into an automated pipeline.
- Close with a concrete example from your own work: which phase you owned, which artefact you produced, and one thing that went wrong in a phase and how the process caught it.
Follow-up
- When would you choose waterfall over Scrum for a project?
- Where does testing sit in an Agile sprint, and who owns it?
- How does maintenance feed back into requirements for the next cycle?
What are the key differences between RESTful and SOAP web services?
What are the key differences between RESTful and SOAP web services?
Approach
- Open with the category difference: SOAP is a protocol with a fixed XML envelope (header and body) and a WSDL contract, while REST is an architectural style built on resources identified by URIs and manipulated through a uniform HTTP interface.
- Cover transport and format: SOAP messages are always XML and can travel over HTTP, SMTP or JMS, usually as HTTP POST; REST normally uses HTTP directly and can return JSON, XML or other representations negotiated through Content-Type and Accept headers.
- Cover HTTP semantics REST gets for free: GET, PUT and DELETE are idempotent and POST is not, GET responses can be cached by browsers and proxies, and status codes (404, 409, 503) carry errors, where SOAP reports errors in a Fault element.
- Name where SOAP still wins: the WS-* standards give message-level security (WS-Security), reliable delivery and distributed transactions, and a WSDL lets tools generate typed client code, which is why many enterprise and ERP integrations still use it.
- State the trade-off plainly: REST is lighter, easier to call from a browser or mobile client and documented with OpenAPI; SOAP is heavier but carries a strict contract. Pick based on the consumer and the contract requirements, not fashion.
Follow-up
- What makes PUT idempotent and POST not, and why does that matter for retries?
- How would you version a REST API without breaking existing clients?
- How would you wrap an existing SOAP service behind a REST endpoint?
Describe a challenging technical problem you solved and the approach you took.
Describe a challenging technical problem you solved and the approach you took.
Approach
- Pick a problem with real technical depth (a race condition, a slow query, a memory leak, a failing integration), and state the symptom and its impact with a number: error rate, latency, hours of downtime or affected users.
- Walk through the diagnosis in order: what you measured first, the hypotheses you ruled out and the evidence that ruled each one out, so the listener can follow your reasoning rather than just hear the answer.
- Name at least two fixes you considered and why you chose one: cost, risk, time to ship, or what it would break elsewhere.
- Give the result in measurable terms and say how you verified it (a load test, a before-and-after metric, a regression test that now guards the bug).
- End with what you changed afterwards (monitoring, a code review rule, a shared library fix). The answer that sinks is a vague story where the team did everything and your own decisions never appear.
Follow-up
- What would you do differently if you met the same problem again?
- How did you confirm the fix addressed the root cause and not just the symptom?
- Who else did you need to convince, and how?
How do you ensure code quality and maintainability?
How do you ensure code quality and maintainability?
Approach
- Start with automated gates in CI: unit and integration tests on every pull request, a formatter (Black, Prettier, dotnet format) and static analysis (ruff or pylint and mypy for Python, SpotBugs or Checkstyle for Java, Roslyn analyzers for C#), so style debates never reach review.
- Describe how you review code: small pull requests, a clear description of intent, and review comments focused on correctness, naming, error handling and test coverage of the changed behaviour rather than personal style.
- Explain the design habits that keep code maintainable: single-responsibility classes and functions, dependency injection so units can be tested in isolation, and no duplicated business rules.
- Treat coverage as a signal, not a target: high line coverage with no assertions proves nothing, so check that tests cover branches and failure paths that matter.
- Mention how you pay down debt: refactoring under test as part of normal work, recording design decisions in short ADRs or README sections, and tracking hotspots (files changed most often with the most bugs).
Follow-up
- How do you handle a teammate who repeatedly pushes back on review comments?
- What would you do with a legacy module that has no tests and must be changed?
- Which code-quality metric would you refuse to set a target on, and why?
Describe your process for evaluating potential solutions to a technical challenge.
Describe your process for evaluating potential solutions to a technical challenge.
Approach
- Pin down the requirements and constraints first: functional needs, non-functional targets (latency, throughput, availability, cost), deadlines, and the skills the team already has in Java, C#, Python or whatever the codebase uses.
- Generate at least two or three real options, including the cheapest one (reuse an existing component, buy rather than build, or change nothing), so the comparison is not a straw man.
- Compare them on explicit criteria, optionally a weighted decision matrix: complexity, operating cost, risk, maintainability and how hard the choice is to reverse later.
- Retire the biggest unknown with a short spike or prototype instead of debating it, for example a load test of the candidate database or a proof of concept against the real API.
- Record the decision and the rejected options in a short design record, and say what result would make you revisit it.
Follow-up
- Give an example where the option you rejected turned out to be the better one.
- How do you decide when a prototype has answered enough?
- How do you settle a disagreement when two engineers weight the criteria differently?
Provide an example of a project where you had to pivot your strategy based on feedback.
Provide an example of a project where you had to pivot your strategy based on feedback.
Approach
- Set up the original plan and why it looked right at the time, in two or three sentences, so the change of direction has context.
- Name the feedback precisely and its source: user testing, a performance measurement, a code review, a stakeholder demo or a production incident.
- Show how you checked the feedback before acting on it (data, a second opinion, a quick experiment) and how you weighed the cost of changing course against carrying on.
- Describe what you changed technically and how you limited waste: what you kept, what you threw away, and how you reset the timeline with stakeholders.
- Close with the measurable outcome and what you now do earlier to get that feedback sooner. The story that sinks is one where you resisted the feedback until it was forced on you, or where you blame whoever gave it.
Follow-up
- What would you have lost if you had ignored the feedback?
- How did you tell stakeholders the timeline had changed?
- How do you now collect feedback earlier in a project?
What metrics would you use to measure the success of a software project?
What metrics would you use to measure the success of a software project?
Approach
- Separate outcome metrics from delivery metrics: outcomes are whether the software did its job (adoption, task completion rate, process time saved, defects reported by users), delivery is how well the team shipped it.
- For delivery, name the four DORA metrics: deployment frequency, lead time for changes, change failure rate and time to restore service after a failure.
- For quality and operations, add defect escape rate (bugs found after release versus before), availability and latency percentiles (p95, p99) against an agreed service-level objective.
- Include schedule and scope: delivered scope against plan and how often estimates were missed, but explain why story-point velocity should not be compared across teams.
- Warn about gaming: lines of code or raw coverage percentages become targets and stop measuring anything (Goodhart's law), so pair each speed metric with a quality metric.
Follow-up
- Which single metric would you report to a non-technical stakeholder, and why?
- How would you measure success for an internal tool with no revenue attached?
- What would you do if delivery metrics improved but users were still unhappy?
How would you approach debugging a complex software issue?
How would you approach debugging a complex software issue?
Approach
- Reproduce first: get the exact inputs, environment and version where it fails, and reduce it to the smallest case that still fails. A bug you cannot reproduce you can only guess at.
- Gather evidence before theorising: logs around the failure, metrics (error rate, latency, memory), stack traces and recent changes in code, configuration, data or dependencies.
- Narrow the search systematically: use git bisect to binary-search the commit history (about log2 of the number of commits in steps), or disable components one at a time to isolate the layer that fails.
- Form one hypothesis at a time and test it with a debugger, breakpoints or targeted logging. For intermittent bugs such as race conditions, note that extra logging can change timing, so run the case in a loop or under stress to confirm.
- Fix the root cause, add a regression test that failed before the fix, and record what monitoring or check would have caught it sooner.
Follow-up
- How would you debug something that only happens in production and never locally?
- How do you tell a cause from a coincidence in the logs?
- What do you do if the bug is in a third-party library?
Seven days built around the two reported stages and the stack candidates list: fundamentals and coding first, then project stories, then behavioral rehearsal and a full run-through. Questions are grouped by type because candidates do not tie them to stages.
Prepare, practise & reflect
One practical outcome each day. Spend longer where you need it.
0 / 7 done01Map the loop and your experience
- Write out the two reported stages, the phone screening and the in-person interviews with hiring managers and team members, and note what each needs from you.

Practice prompt ↗Practice prompt ↗Expand any day for tasks and deliverables. Your progress is saved on this device.
The behavioral questions candidates report cover conflict, motivation, contribution to a team, prioritization under deadlines and learning quickly. Each needs a specific story from your own work, told in the first person with the situation, what you did and the result. Version control experience is filed with these questions too, so have concrete examples of how you used it with a team.
Discuss your experience with version control systems.
Discuss your experience with version control systems.
Approach
- Name the systems you have used (Git is the common one; add Subversion, TFS or Perforce if relevant) and the workflow you actually follow: feature branches, pull requests, a protected main branch, required review and passing CI before merge.
- Show you understand merge versus rebase. Merge preserves history and is safe on shared branches; rebase gives a linear history but rewrites commits, so you only rebase branches nobody else has pulled.
- Tell one concrete recovery story: resolving a merge conflict by reading both sides and re-running tests, using git bisect to find the commit that broke a build, or using git revert to undo a change already on a shared branch instead of a reset and force push.
- Cover release hygiene: small commits with clear messages, tags for releases, hotfix branches, and how version control connects to code review and CI in an Agile team. Anchor the answer in a team situation, not a list of commands.
Follow-up
- When would you choose rebase over merge, and when would you never rebase?
- A teammate force-pushed over your commits. How do you recover the work?
- Would you pick trunk-based development or long-lived feature branches for a team that releases often, and why?
Describe a time when you had a conflict with a team member. How did you resolve it?
Describe a time when you had a conflict with a team member. How did you resolve it?
Approach
- Pick a real disagreement about work, such as a design approach, review comments or priorities, not a personality clash. Set it up in two sentences and say what was at stake for the project.
- Show the steps you took: you listened to their reasoning first, restated their position, named the shared goal (the release, the user, maintainability), and moved the discussion to evidence such as a prototype, a benchmark or an example input. Say whether you took it out of the review thread into a direct conversation.
- State the resolution honestly, including any compromise or any point where you turned out to be wrong, then give the outcome and the state of the working relationship afterwards.
- The mistake that sinks this answer is a story in which the other person was unreasonable and you won. If you escalated, explain why it was appropriate and that you spoke to the person first.
Follow-up
- What would you have done if they still disagreed after that conversation?
- Would you handle it differently today?
- How did you make sure the working relationship held up afterwards?
What motivates you to succeed in your role?
What motivates you to succeed in your role?
Approach
- Give one or two genuine drivers and prove each with past behaviour, for example staying on a recurring failure until it is gone, watching people adopt something you built, or leaving a codebase easier to change than you found it.
- Connect them to the work as candidates describe it: software that supports products and manufacturing and operational processes, built with product, QA and operations colleagues. Say what about that kind of work engages you, based on your own reading of Brady's products rather than guesses.
- Keep it truthful and specific. An answer that is only about pay or title, or a generic love of challenges with no example, gives the listener nothing to remember.
- Close by showing how the motivation appears in daily habits, such as writing tests, documenting decisions or reviewing carefully, so it reads as behaviour and not a slogan.
Follow-up
- Tell me about a time that motivation was tested, for instance on a dull or stalled project.
- What kind of work drains you, and how do you handle it when it comes up?
- How does your motivation change when the team is under deadline pressure?
Give an example of how you have contributed to a team’s success.
Give an example of how you have contributed to a team’s success.
Approach
- Choose a contribution that is clearly yours and concrete: unblocking a release, building a test harness or shared tooling, writing documentation that cut repeat questions, mentoring a new teammate or running a useful retrospective.
- Use situation, task, action, result. State the team goal first, then describe your actions in sentences that start with "I", then give a team-level result that you can measure honestly, such as build time, defect count or a release date met.
- Show collaboration beyond engineering if you can, with QA, product management or operations, because the role works with those groups.
- Avoid a story told only in the plural where your part cannot be separated out, and avoid claiming sole credit. Name what others contributed and how your piece fitted with theirs.
Follow-up
- What did the rest of the team do that you did not, and how did it fit with your part?
- How would the outcome have differed without your contribution?
- What did you learn about working with that team that you would apply here?
How do you prioritize tasks when faced with multiple deadlines?
How do you prioritize tasks when faced with multiple deadlines?
Approach
- State a method, then prove it with an example. List every commitment with its deadline, consequence of slipping, size and dependencies; rank by impact and urgency; separate what only you can do from what can be delegated, shrunk or deferred.
- Communicate early with the people affected and offer a concrete trade-off, such as "I can deliver the fix by Thursday, or the fix and the report by next Tuesday". Ask who decides when priorities genuinely conflict, which in a Scrum team means the product owner and the backlog.
- Use a real example with specifics: what you deferred, what you protected (tests and review should not be the first thing cut), and how it turned out.
- The weak answers are "I work longer hours" and "I never miss a deadline", because neither shows a trade-off or any communication.
Follow-up
- Two stakeholders each say their request is the top priority. What do you do?
- How do you handle an urgent request that arrives in the middle of a sprint?
- Tell me about a time you realised you would miss a deadline. What did you do?
Tell me about a time you had to learn a new technology quickly.
Tell me about a time you had to learn a new technology quickly.
Approach
- Pick a story with a real deadline and real output: a new language or framework (for example moving between Java, C# and Python), a cloud service such as AWS or Azure, or an unfamiliar codebase.
- Describe your method: decide the minimum you needed to be useful, read the official documentation and existing code, build a small vertical slice to prove the approach, write tests as you learn, ask an experienced colleague targeted questions, and seek review early.
- Give evidence: what shipped, how it behaved in production or testing, and how colleagues came to rely on it. Be candid about what you still did not know and how you closed that gap.
- Avoid "I watched tutorials" with nothing delivered, and avoid implying you mastered it overnight. Learning speed is shown by output and by knowing the limits of your understanding.
Follow-up
- How did you decide you understood it well enough to ship?
- What did you get wrong at first?
- How do you choose between learning a new tool and using one you already know?

What does the Brady Software Engineer interview process look like?
Candidates report two stages: a phone screening about your background and fit, followed by in-person interviews with hiring managers and team members. The whole process is reported at roughly 2-4 weeks, depending on scheduling. Treat that as what candidates describe, not a fixed schedule.
PracHub Software Engineer practice ↗Which programming language should I prepare in?
Candidates list Java, C# and Python as examples for the role. Choose the one you write most fluently for any coding exercise, and be ready to discuss projects in whichever of them you have used. The reported string-reversal prompt lets you pick your preferred language.
PracHub Software Engineer practice ↗How hard is the coding portion?
The reported coding prompts are fundamentals: reverse a string, explain the time complexity, handle edge cases, and discuss a data structure you have used. Preparation is about precision, so write clean code, state complexity without being asked, and test empty, single-character, null and multi-code-unit inputs.
PracHub Software Engineer practice ↗Should I prepare system design as well?
Candidates describe questions on system architecture and design patterns among the evaluation areas, and software architecture and design principles appear in the requirements. Be ready to explain the architecture of a project you built, why you chose it, and what you would change, including how its web services were designed.
PracHub Software Engineer practice ↗Do I need to know Brady's products?
Candidates describe the work as software supporting Brady's products and its manufacturing and operational processes, and tips for the role suggest learning the product range. Read what Brady publishes about its own products before the in-person stage, and mention only what you have actually understood.
PracHub Software Engineer practice ↗How much cloud, DevOps and database knowledge do I need?
Candidates list AWS or Azure, DevOps practices and database management and optimization as nice-to-haves, not requirements. Mention them where you have real experience, such as a deployment pipeline or a slow query you tuned, and do not stretch beyond what you can explain in detail.
