Interview Prompt

Surface all sender IDs who have posted more than one message, along with each sender's message count. A downstream anomaly-detection system needs these high-frequency senders.

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
