Interview Prompt
A metrics export comes back as a `grid` of equal-length rows, one row per day and one column per metric. Reorient it so each metric's column becomes its own row.
Summary
Turn the grid on its side and let every column stand up as a row.
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
