Interview Prompt
Our monitoring pipeline emits log lines shaped like '[LEVEL] message', and not all of them survive the trip: some arrive empty, with no brackets, or otherwise garbled. From a batch of those lines, return how often each level appears and which level appears most.
Summary
Some lines repeat themselves.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
