What we test for
Typical work
- Backend services and APIs in TypeScript
- Event-driven work: queues, webhooks, workers
- Moving JavaScript code bases to TypeScript
- Integrations with payment, CRM and auth providers
The coding test
Build a small TypeScript API with validation, error handling and tests, then make a slow endpoint non-blocking. Scored on structure, typing, tests and reasoning about the event loop.
Inside Node.js
The ones people search for by name get a page of their own, with their own coding test and interview questions.
Five interview questions you can reuse
We use questions like these in our soft-skills and technical rounds. Steal them for your own interviews.
What blocks the event loop, and how do you find it?
A strong answer covers: CPU-heavy work, sync I/O, huge JSON; profiling, event-loop lag metrics, moving work to workers or queues.
How do you make a webhook handler safe to retry?
A strong answer covers: Idempotency keys, signature checks, fast acknowledge then process async, dead-letter handling.
Where do you validate input in a TypeScript API?
A strong answer covers: At the boundary with a schema library; types are not runtime checks; shared schemas for docs.
How do you handle errors in async code?
A strong answer covers: No floating promises, central error middleware, typed errors, logging with context.
What does a good pull request look like on your team?
A strong answer covers: Small, one purpose, tests included, a description that explains why, not only what.
