Interview Prompt
Our alerting system treats one-off error codes differently from recurring ones. Write a function called find_singletons that takes a list of server response codes and returns only the codes that appeared exactly once, preserving their original order.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your python solution with real code execution
- Get instant feedback and a hire/no-hire decision
