At Veho, a Software Engineer does not just write code; they build the digital backbone of a modern, tech-enabled logistics platform. Veho is redefining the last-mile delivery experience by combining cutting-edge technology with an asset-light driver marketplace and highly efficient warehouse operations. As a engineer here, your work directly impacts the real-time routing engines, driver mobile applications, and warehouse management systems that ensure packages are delivered on time, every time. The engineering team at Veho solves complex, high-scale physical and digital challenges. You will work on distributed systems that process massive amounts of location, routing, and inventory data. Whether you are optimizing a machine learning model for route efficiency, scaling an event-driven microservices architecture on AWS, or improving the user experience for independent delivery drivers, your contributions will have a visible and immediate impact on the company’s operational efficiency and customer satisfaction. This role requires a unique blend of deep technical expertise, operational empathy, and a passion for solving real-world logistics problems. values engineers who are collaborative, highly analytical, and capable of navigating ambiguity in a fast-growing startup environment.

Going into the loop without having done this.
To maximize your chances of success during the Veho interview process, keep these practical, insider tips in mind:
Going into the loop without having done this.
Show Operational Empathy: Veho is a physical logistics business powered by software. When designing systems or writing code, always consider the end-users—such as warehouse operators sorting packages or drivers navigating tight delivery windows. Frame your technical decisions around how they improve real-world operations.
Going into the loop without having done this.
Be Explicit About AWS Trade-offs: During system design discussions, do not just list AWS services. Explain why you chose a specific service over another. For example, discuss why you would choose DynamoDB for low-latency key-value lookups versus PostgreSQL for complex relational queries.
Going into the loop without having done this.
Structure Your Behavioral Answers: Use the STAR method (Situation, Task, Action, Result) to structure your behavioral responses. Be specific about your individual contributions and highlight the quantitative business or operational impact of your work.

- 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?

Explain how you would use AWS Lambda and Amazon SQS to build an asynchronous, event-driven order processing pipeline.
Approach

Denormalise tenant onto revisions and backfill it live
resource_revision (revision_id, resource_id, version, actor_user_id, change_kind, patch, request_id, created_at) has 400M rows and no tenant column; tenant_id lives only on resource. Two reads need it: a tenant-scoped audit feed ordered by created_at DESC, and an offboarding purge. Both join back to resource today. Justify adding tenant_id to resource_revision against those two reads, name the anomaly the copy introduces and the constraint that prevents it, then give the ordered migration for a live table taking 1.2k writes/second — the lock each step takes, how the backfill is batched, and where each step stops being reversible. PostgreSQL 16.
Approach
- Justify from the access path rather than from taste. Without the column, the audit feed either scans resource_revision by created_at and discards other tenants' rows, or resolves the tenant's resource_ids first and probes with them — both proportional to the tenant's whole history rather than to one page. With (tenant_id, created_at DESC, revision_id DESC) it is a seek that stops at 50 rows, and the purge becomes a ranged delete instead of a join.
- Name the cost exactly: a second copy of a fact can disagree with the first. Make the disagreement unwritable rather than documented — add UNIQUE (resource_id, tenant_id) on resource so it can serve as a foreign-key target, then FOREIGN KEY (resource_id, tenant_id) REFERENCES resource (resource_id, tenant_id) on the revision table. A revision can then only ever carry its parent's tenant.
- Step one, expand: ALTER TABLE resource_revision ADD COLUMN tenant_id BIGINT NULL, with no default, so it is a catalogue change and no rewrite. It still needs ACCESS EXCLUSIVE for an instant, and that instant queues behind the longest open transaction on the table while every later query queues behind it — set lock_timeout to 2s and retry rather than wait.
- Step two, dual-write: deploy the writer that populates tenant_id on every new revision while reads still use the join. Reversible by redeploying the previous build, because nothing reads the column yet.
Follow-up
- The backfill is half finished and a rollback is required. What state is the table in, and what does the previous build do with a half-populated column?
- How do you verify the backfill actually finished, given rows are still being inserted while it runs?
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?
- A dashboard runs this for 40 owners in one page load. What changes about the design?
