PracHub editorial advice for the preparation topics above.
Own your resume
Do not list a technology if you cannot explain it in depth. Interviewers will pick the most complex item on your CV and ask you to explain it from first principles.
Prepare for the "Why
Be ready to explain why you chose a specific technology over an alternative. Seagate values engineers who understand the trade-offs in their design decisions.
Ask insightful questions
Use the time at the end of the interview to ask about the team’s current technical challenges or the product lifecycle. It shows you are thinking like a future colleague.
Be honest about limitations
If you don't know the answer to a highly specific technical question, it is better to explain how you would find the answer than to guess.
Choose a category, try a prompt, then open its approach, worked solution or follow-up when you need it.
How do you optimize C/C++ code for memory-constrained environments?
How do you optimize C/C++ code for memory-constrained environments?
Approach
- Say what the runtime actually does before reasoning about the code.
- Name what is shared across threads and what owns each piece of state.
- Identify the window where an invariant is briefly untrue.
- Distinguish a value from a reference to it, and say which one you handed out.
Follow-up
- What happens if two callers reach this at the same time?
- Where could this allocate more than you expect?
Explain the logic behind managing linked lists or sorting algorithms in a hardware-adjacent context.
Explain the logic behind managing linked lists or sorting algorithms in a hardware-adjacent context.
Approach
- Restate the input: its shape, its size, and what is guaranteed about it.
- Name the brute-force solution and its complexity before improving on it.
- Choose the data structure from the access pattern, not from familiarity.
- State the target complexity and say which constraint rules the naive version out.
Follow-up
- How does this change if the input no longer fits in memory?
- What is the worst case, and how likely is it on real data?
Merge partitioned event streams into one ordered feed with bounded lateness
The read-model service consumes 64 log partitions carrying about 4,000 events per second in total. Each partition is ordered within itself, but partitions drift by up to 30 seconds, and the activity feed must present a tenant's events in occurred_at order. Produce the merge. State its complexity, the buffer it requires in events and in bytes, what happens when one partition is idle, and what you do with an event that arrives after you have already emitted its position. Payloads average 1 KB.
Approach
- Merge with a min-heap over the 64 partition heads keyed on (occurred_at, event_id): O(log P) per event and O(n log P) overall. The tie-break on event_id is what makes the output deterministic when two partitions carry the same millisecond, which matters because the feed is paginated and a non-deterministic order reorders pages under the reader.
- Emitting the heap head is only correct once every partition has produced everything up to that timestamp, so the emit condition is a watermark: the minimum across partitions of the highest occurred_at seen, less the allowed lateness. Events are held until the watermark passes them, which is what turns individually ordered streams into a jointly ordered one.
- Size the buffer from the lateness rather than guessing: 4,000 events per second times 30 seconds is 120,000 buffered events, and at 1 KB each about 120 MB of heap. That number is the real price of the ordering guarantee and belongs in front of whoever asked for it.
- Handle the idle partition explicitly, because it fails the feed rather than corrupting it: a partition with no traffic never advances its own maximum, so the watermark freezes and output stops entirely. Either every partition emits a periodic idle marker carrying the broker's current time, or the watermark falls back to wall clock for a partition silent beyond a threshold.
Follow-up
- The lateness budget is raised to five minutes. What is the new buffer, and what besides memory changes?
- The consumer restarts. Where does it resume from, and what does the feed look like for the first 30 seconds?
Stop tag and share joins from fanning out a page
resource_tag is (resource_id, tag_id) with PK (resource_id, tag_id); resource_share is (resource_id, shared_with_user_id, permission). The tagged-and-shared listing inner-joins resource to both, filters tenant_id, tag_id = ANY($2) and shared_with_user_id = $3, orders by updated_at DESC and takes 50. Pages come back with fewer than 50 distinct resources and the total in the header is far too high. Explain the row multiplication, rewrite both the page query and the count query so each is correct, and name the index each one needs. PostgreSQL 16.
Approach
- Do the arithmetic against the predicates that are actually there. An inner join emits one row per matching child row, and both joins are filtered: tag_id = ANY($2) admits only the requested tags, shared_with_user_id = $3 admits one user's share rows. So a resource holding three of the requested tags and shared with $3 once yields three rows, not one — the multiplier is its count of matching tags times its share rows for that single user, and that second factor is 1 unless the table admits duplicate (resource_id, shared_with_user_id) pairs. LIMIT 50 then limits rows rather than resources, and COUNT(*) counts pairs — the header is the product, not the population.
- Reject DISTINCT as the fix. It deduplicates after the product has been built, so the planner must materialise and sort the fanned-out set before the LIMIT can apply, and it leaves any SUM or AVG in the same select list wrong.
- Rewrite both filters as semi-joins, keeping resource as the only row source: AND EXISTS (SELECT 1 FROM resource_tag rt WHERE rt.resource_id = r.resource_id AND rt.tag_id = ANY($2)) and the same shape against resource_share. A semi-join stops at the first match per resource and preserves the driving index order, so ORDER BY updated_at DESC, resource_id DESC LIMIT 50 still stops after 50 rows.
- Count with the same predicates and no join at all: SELECT count(*) FROM resource r WHERE r.tenant_id = $1 AND r.status = 'active' AND EXISTS (...) AND EXISTS (...). Nothing multiplies a resource, so the number is the population.
Follow-up
- The filter changes from 'any of these tags' to 'all of these tags'. Rewrite it and state what it costs relative to the ANY form.
- A resource can be shared with the same user twice under different permissions. Does your count change, and should it?
Find version gaps and relay lag with window functions
outbox_event holds event_id, aggregate_type, aggregate_id, aggregate_version, event_type, payload, status ('pending','published','dead'), attempts, created_at, published_at. A projection is missing rows and you must decide whether the relay skipped events or the consumer dropped them. Write three queries over the last seven days: one listing every aggregate_id whose published aggregate_version sequence has a hole, one giving per-day counts with a running total, and one returning the newest published event per aggregate. For each, say where the window function is evaluated relative to WHERE and LIMIT. PostgreSQL 16.
Approach
- Gaps: compute lead(aggregate_version) OVER (PARTITION BY aggregate_id ORDER BY aggregate_version) in a subquery, then filter next_version <> aggregate_version + 1 in the outer query. Window functions are evaluated after WHERE, GROUP BY and HAVING and before the outer ORDER BY and LIMIT, so the predicate cannot sit in the same WHERE clause and PostgreSQL 16 has no QUALIFY.
- Say what the seven-day filter does to the answer: it truncates every partition, so the first row per aggregate has no predecessor inside the window and a hole spanning the boundary is invisible. Widen the window, or join to resource.version as the authority for the true maximum.
- Running total: SELECT date_trunc('day', created_at) AS d, count() AS n, sum(count()) OVER (ORDER BY date_trunc('day', created_at) ROWS UNBOUNDED PRECEDING). An aggregate inside a window call is legal because grouping runs before windowing. The grouping key is unique per row here so ROWS and RANGE agree, but write the frame anyway — over ungrouped rows with tied timestamps the default RANGE frame pulls in every peer row and the total jumps.
- Newest per aggregate: DISTINCT ON (aggregate_id) ... ORDER BY aggregate_id, aggregate_version DESC is the cheap PostgreSQL-only form when an index matches that order; row_number() OVER (PARTITION BY aggregate_id ORDER BY aggregate_version DESC) = 1 is the portable form and needs a subquery for the same evaluation-order reason as the gap query.
Follow-up
- Relay failover redelivers events. Does a duplicate break the gap query, and how would you detect one from this table alone?
- Turn the gap check into a continuous monitor rather than a query someone runs after an incident. What does it watch?

How long does the interview process usually take?
Timelines vary significantly by location and team, but expect a process that spans several weeks. Be prepared to be patient, as coordination across multiple engineering teams can take time.
Seagate Software Engineer candidate reports ↗Is the interview process very difficult?
It is generally described as average to difficult. The key is that it is often more conversational than a "whiteboard-only" test, focusing heavily on your actual experience and how you solve real-world problems.
Seagate Software Engineer candidate reports ↗Should I prepare for coding tests?
Yes. While many interviews are conversational, you should be ready to write code—either on paper, a whiteboard, or in a shared digital document—to demonstrate your logic and mastery of C/C++.
Seagate Software Engineer candidate reports ↗Does Seagate offer remote work?
This depends on the specific team and location. It is best to clarify this during your initial recruiter screen, as many roles require close interaction with physical lab hardware.
Seagate Software Engineer candidate reports ↗How many interview rounds does Seagate have for a Software Engineer, and what are the stages?
Seagate’s Software Engineer process starts with a recruiter screen, then moves into multiple technical assessments and behavioral assessments. After that, the process typically includes team interviews with several engineers and managers from the group you would join. Expect the structure to be thorough and team-centric.
Seagate Software Engineer candidate reports ↗How hard are Seagate Software Engineer interviews, and what does the difficulty level mean in practice?
In candidate-reported results for Seagate Software Engineer interviews, the most common difficulty level is average. With that level, you should still expect a resume-driven approach in early rounds and deeper technical questioning in later stages. Team interviews can also add pressure because you are evaluated by people close to the specific work.
Seagate Software Engineer candidate reports ↗What technical topics does Seagate test for Software Engineer interviews?
You should be ready for C programming and C preprocessor macros, plus bitwise operators. Domain topics that come up include digital hardware or HDD technology knowledge, and storage protocols like SATA, SAS, and NVMe. The process also tests core engineering fundamentals through systems and kernel-adjacent areas like Linux kernel development or driver patching, and it often includes SIP protocol questions.
Seagate Software Engineer candidate reports ↗Do Seagate Software Engineer interviews focus more on behavioral questions or technical questions?
Both matter. The process explicitly includes behavioral assessments to evaluate fit and communication, and it also includes multiple technical assessment rounds focused on specialized skills. One preparation priority is having strong stories from your resume for resume deep-dive and behavioral-style questions.
Seagate Software Engineer candidate reports ↗What should I prioritize when preparing for Seagate Software Engineer interviews?
Prioritize being able to explain the why and how behind what you did in your resume, since interviewers frequently use your CV as a roadmap for technical questioning. Be ready to verbalize your process for complex scenarios, including how you identify constraints and propose iterative improvements. Also review how hardware and software interface, since Seagate values candidates who understand that interaction even when the role is software-focused.
Seagate Software Engineer candidate reports ↗What is the typical pay for a Seagate Software Engineer, and does it vary?
Your Seagate compensation varies by level and location, and you may see different figures across job-posting and candidate reports. The interview difficulty most often shows up as average in candidate reporting.
