Interview Prompt

Exponential backoff in one sentence: each successive retry waits roughly twice as long as the previous one (base * 2^attempt), capped at a maximum, with jitter applied. Without a cap the seventh retry waits 64 seconds, the tenth waits 512, the fifteenth waits four hours. The cap is non-optional. Compute the wait by replacing the retry transform with one whose name states the formula's three knobs: base, cap, and a jitter strategy.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your pipeline design solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
