Interview Process
The interview consisted of three back-to-back rounds. The problems were not particularly difficult, but the candidate felt rusty with Python. The need to explain while coding led to missing details, resulting in several bugs during testing. The candidate highlighted the importance of paying attention to input formats and specific attribute details in the code to avoid mistakes.
Technical Questions
