Interview Prompt

A trading feed hands you a day's prices in the order they were captured, and we want the largest gain a single buy-then-sell could have booked.

Summary

You only get to buy before you sell. Find the biggest gain the day allowed.

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
