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
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Python against test cases
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
