Interview Prompt

A permission service replays a stream of access changes: `grant` and `revoke` add or drop a single permission for one user, `check` asks whether a user currently holds a given permission, and `update_config` hands over a whole user-to-permissions mapping. Return the boolean answer to each `check`, in order.

Summary

When the roster changes, does access follow?

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write and run your Python against test cases
  4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
