Interview Prompt

A hot parity check runs on every record in a tight loop, and profiling flagged the modulo it uses as the bottleneck. Given an integer `n`, return whether it is even, without using the modulo operator.

Summary

Is this number in the even club? Prove it the fast way.

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
