Interview Prompt
We're shrinking repetitive log lines before they land in cold storage. Collapse each stretch of the same character in a row into that character followed by how many times it repeats there, and return the compacted string.
Summary
Say it once, then say how many times it kept saying it.
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
