Interview Prompt
Each row in `user_sessions` is one session logged against a `user_id` from `users`, and some accounts have never logged a single one. Return the user ID and username of every account with zero session history.
Summary
Sprint started. Some people never got assigned.
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
