Vetting

How we vet API Developers

Every API developer sits the Cubehire AI interview: multiple choice fundamentals, a timed written and coding round, and a recorded video round. A person on our team then reviews the profile before any company sees it. For this role, the interview checks that they can:

  1. Check 1

    Designs a versioned API with pagination, errors and authentication in the written round.

  2. Check 2

    Handles duplicate webhook deliveries and partial failures safely in a coding task.

  3. Check 3

    Explains OAuth flows and how to store and rotate third party credentials.

Questions about hiring API Developers

What companies ask before they hire a API developer through Cubehire.

Talk to our team
They design APIs other software uses to talk to your product, and they connect your product to outside services such as payments, CRMs and accounting tools, making sure data moves reliably and securely.
REST is simpler to cache and widely understood, which suits public APIs. GraphQL suits complex frontends that need flexible queries. Our developers recommend based on who consumes the API.
Yes. Reverse engineering undocumented or older SOAP and XML APIs is a normal part of integration work, with tests written against real responses.
Retries with backoff, idempotency keys, webhook signature checks, monitoring and alerts on failure rates, so problems surface before customers report them.
A flat rate quoted before you interview anyone: a one time fee for full time placements, or a fixed monthly rate for contract work. There is no percentage of salary. See the pricing page for current rates.
