Interview Prompt
Every training run our ML platform kicks off lands as a row in ml_models, and some models get retrained far more than others. Ignoring the runs that failed outright, find the models that have been retrained heavily, along with how many runs each one racked up.
Summary
Same model, trained twice.
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
