Interview Prompt
Each row of `err_tracks` is one tracked error, and its `count` column holds how many times that error fired. Put every track into a 'timeout' category when its error type mentions a timeout, 'memory' when it mentions memory, and 'other' otherwise, then report how many tracks land in each.
Summary
Postmortem time. Categorize the errors.
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
