Interview Prompt

A sharding step splits records across two partitions by whether their integer key `n` is even. Return `True` for an even key and `False` for an odd one, deciding it with bitwise operations only: no `%`, `/` or `//`.

Summary

No division, no modulo - just a single bit tells you everything.

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
