Embrace Flexibility
Akido highly values candidates who are adaptable. If an interviewer changes the constraints of a system design question halfway through, roll with it enthusiastically. Show that you view changing requirements as a puzzle to solve, not a frustration.
Focus on the Product
Candidates who express genuine love for the company's culture and products stand out. Take time before your interview to deeply research what Akido builds, and weave that enthusiasm into your behavioral answers.
Always clarify the constraints before writing any code
Interviewers at Akido intentionally leave prompts vague to see if you will ask questions about input size, data types, and edge cases.
Think Out Loud
Silent coding is a red flag. Treat the technical screens as pair-programming sessions. Explain your logic, discuss the time and space complexity of your approach, and ask the interviewer for their thoughts before you optimize.

Explain how you would safely migrate millions of user records from a legacy SQL database to a NoSQL solution w
Explain how you would safely migrate millions of user records from a legacy SQL database to a NoSQL solution with zero downtime.
Approach
- Name the grain you start from and join outward from it.
- Check whether any join is one-to-many before aggregating, or the sums inflate.
- Say which index the query would use, and what makes it unusable.
- Handle the rows that do not match: that is usually the actual question.
Follow-up
- How does the query change if that join becomes one-to-many?
- What happens to this when the table is ten times larger?
Explain why the owner filter ignores the listing index
The only index on resource is (tenant_id, status, updated_at DESC, resource_id DESC). A new endpoint returns one user's resources across all statuses, newest created first: WHERE tenant_id = $1 AND owner_user_id = $2 ORDER BY created_at DESC LIMIT 20. On a tenant with 2M rows it takes 900 ms and EXPLAIN shows a sort above a large scan. Explain precisely why the existing index cannot serve it, give the index that can, and state which of these the new index still will not help: owner_user_id alone across tenants; the same query ordered by updated_at. PostgreSQL 16.
Approach
- Separate the two jobs an index does. For filtering, a composite btree is seekable only on a left prefix, so with no predicate on status the scan can at best range over tenant_id and test owner_user_id per row; PostgreSQL 16 has no btree skip scan to jump the unconstrained column.
- For ordering, the index is sorted by (status, updated_at) within a tenant and not by created_at, so the LIMIT cannot stop early: every matching row is read and then sorted. That is the 'Sort Method: top-N heapsort' line, and it is why the plan reads 2M rows to answer with 20.
- Derive the replacement from the access path — equality, equality, then the ordering column: CREATE INDEX CONCURRENTLY ON resource (tenant_id, owner_user_id, created_at DESC). The scan seeks to the (tenant, owner) range and walks 20 entries in order, so the Sort node disappears along with the row-read.
- Treat INCLUDE (title, status) as conditional, not free. An index-only scan still visits the heap for any row whose page is not marked all-visible, so on a table taking 1.2k writes/second the win depends on autovacuum keeping the visibility map current, and the wider index costs more on every insert.
Follow-up
- 90% of rows are status='active'. Would a partial index WHERE status = 'active' change your answer, and for which of the three queries?

Listing latency scales with page size, not with filters
The tenant listing endpoint reads resource filtered by tenant_id and status, ordered by updated_at DESC, and returns each row plus the owner's display name from app_user and the actor of that resource's latest resource_revision. p99 is 55 ms at 10 rows per page and 1.4 s at 200. Database telemetry shows 401 statements per request, each under 1 ms, and nothing in the slow-query log. Diagnose the cause and give the fix, stating the statement count per request and the p99 you expect afterwards.
Approach
- Read the counters before forming a theory. 401 statements for 200 rows is one driver query plus two per row, and sub-millisecond execution with an empty slow-query log rules out a bad plan. The time is round trips, which is why it is invisible in every per-query metric and scales with rows returned rather than with filter selectivity.
- Name the two per-row statements from their normalised text: a single-row app_user lookup by user_id, and a resource_revision lookup by resource_id ordered by version DESC LIMIT 1. Confirm by dropping those two response fields and watching the statement count fall to one. That locates the calls in the serialisation layer, not the repository.
- Check that the arithmetic accounts for the whole gap. Measure one round trip to the replica in isolation; 400 trips at roughly 3 ms of network plus 0.2 ms of execution is about 1.3 s on top of a 55 ms baseline, which matches. If the multiplication had fallen short, the N+1 would only be part of the story and you would keep looking.
- Batch both lookups. Collect owner_user_ids and resource_ids from the driver query, then issue WHERE tenant_id = $1 AND user_id = ANY($2) for the users, and PostgreSQL's SELECT DISTINCT ON (resource_id) ... WHERE resource_id = ANY($2) ORDER BY resource_id, version DESC for the latest revision, which the UNIQUE (resource_id, version) index serves directly. On an engine without DISTINCT ON, use a lateral join or a row_number window. Three statements per request at any page size.
Follow-up
- The page size is capped at 200 today. What breaks first if it is raised to 2,000, and is it still this bug?
- How do you stop the next N+1 from reaching production, given that no individual query is slow and the endpoint's tests pass?

How rigid is the interview process at Akido?
The process is actually highly flexible and candidate-focused. If the hiring team feels you are a strong cultural and technical fit, they will often work with you to find the right role or team, even if the original position you applied for changes or closes.
Akido Software Engineer candidate reports ↗What is the culture like for Software Engineers?
Engineers at Akido describe the culture as deeply collaborative, mission-driven, and supportive. There is a strong emphasis on building products that matter, and leadership is known to be transparent and open to negotiating fair titles and compensation for the right talent.
Akido Software Engineer candidate reports ↗How much should I prepare for System Design versus LeetCode-style questions?
You should balance both, but the emphasis shifts depending on your experience level. Mid-level to senior candidates will face heavy scrutiny on system design and architecture trade-offs. For coding, expect practical, medium-difficulty algorithmic questions rather than obscure brainteasers.
Akido Software Engineer candidate reports ↗What is the typical timeline from the initial screen to an offer?
The timeline generally spans three to four weeks. Because the team is highly communicative, they usually provide prompt feedback after the virtual onsite rounds, especially if they are exploring alternative team placements for you.
Akido Software Engineer candidate reports ↗Are the interviews conducted in a specific programming language?
Akido is generally language-agnostic during the interview process. You are encouraged to use the language you are most comfortable with, provided you can explain its specific nuances, standard libraries, and memory management principles.
Akido Software Engineer candidate reports ↗What topics does Akido test in interviews?
Akido interviews most often cover Stakeholder Management, Program Management, Interview Process Navigation, Communication, and Expectation Management. The exact emphasis depends on the specific role you apply for.
