Vetting

How we vet Database Developers

Every database 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

    Reads an execution plan and fixes a slow query in a practical task.

  2. Check 2

    Designs a schema with constraints and explains normalization trade offs.

  3. Check 3

    Plans a large table migration that avoids locking production.
