Interview Prompt

Our operations team runs a bike-share network across dozens of cities. We want to predict hourly demand at each station so we can pre-position bikes before rush hour. The data comes from multiple city systems and external sources in different formats. Design a pipeline that takes in this raw data and produces reliable, model-ready features.

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
