Interview Prompt

A systems design exercise requires implementing a first-in-first-out queue using only two stacks (Python lists), without using any queue library. Implement push, pop, peek, and empty operations. The amortized time for each operation should be O(1).

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 python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
