Interview Prompt
A URL shortener turns each new link's sequential row id into a compact slug. Encode a non-negative integer `n` into its base 62 representation as a string, using the digits plus lowercase and uppercase letters.
Summary
Every link needs a slug small enough to type by hand.
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
