Interview Prompt
Our session service is supposed to cap how many sessions a user can hold, but the cap was never enforced when sessions were written. Find the users who break it, with each one's session count.
Summary
Somewhere after the third visit, a habit quietly forms. Find the ones who crossed over.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
