Interview Prompt

Count CI builds triggered by merges in 2026. A build is merge-triggered if the trigger is not 'manual'. Show the count (as both integer and decimal) and average build duration separately for the 'main' branch and the 'release' branch.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
