How were errors handled?
Practice this questionDiscussion template: use your own project facts, ownership, and measured outcomes. Bracketed text is a placeholder.
Short explanation:
Error handling defines what happens when inputs, business rules or dependencies fail. A reliable API returns an appropriate response while preserving enough internal context for diagnosis. The answer should describe actual behavior rather than promise that errors were simply “handled centrally.”
Key points:
-
“We handled expected errors with [actual status/error format] and logged unexpected failures.”
-
Describe the real logging approach; keep tokens and personal data out of logs.
-
Give one expected error and one unexpected failure, including the status, user-visible message and logging approach.
Interview point:
- Explain how the code avoided swallowing failures or exposing internal stack traces to clients.
