Interview Prompt

The growth team is building a clean user roster for outreach, but the 'admin' and 'system' accounts need to be excluded, as do users with a 'z' anywhere in their email address (a known test-account pattern). Return every remaining user's full profile, alphabetical by username.

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
