Interview Prompt
A Semaphore caps how many fetches run at once. You have 10 fetches, each taking 1.0s of wait, and a concurrency limit of 3. They run in waves of at most 3; total time = number_of_waves * 1.0s. Compute and print the number of waves and the total seconds (1 decimal), one per line. (Model it, no asyncio.)
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your python solution with real code execution
- Get instant feedback and a hire/no-hire decision
