Interview Prompt
An on-call engineer is replaying a batch of recorded `[name, args, kwargs]` calls against the starter's `OPERATIONS`, with `clock` holding the timer readings taken around those calls and `defaults` holding each operation's usual settings. Report each call's name, what it returned, and how long it took.
Summary
Wrap any function to capture how long it takes.
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
