Interview Prompt
A storage layer holds long status strings where the same character tends to repeat in stretches, and we want a compact form of `s`. Replace each stretch of one repeated character with that character followed by how many times it repeats in a row.
Summary
Say it once, then say how many times it stayed.
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
