Interview Prompt

We want to see which users activated early. Surface users who recorded at least one session within 365 days of signing up, showing user ID, signup date, and session count in that window. Users with zero sessions in their first year should not appear.

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
