Interview Prompt

While debugging a routing issue, an engineer needs to locate where the letter 'a' first appears in each API endpoint string (case-insensitive). Show the endpoint and the character position, excluding endpoints that don't contain 'a' at all, ordered by call ID.

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
