Interview Prompt
Auditing free-text fields in a data export, you need the longest contiguous stretch of a string `s` that reads the same forwards and backwards.
Summary
Somewhere in the noise, a stretch that mirrors itself. Find the longest one.
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
