Technical Coding Behavioral
The interview process started with a brief 30-minute session that was a mix of introductory and semi-technical questions. Following that, there was a coding task to be completed offline, taking about 2 hours. The process concluded with a technical interview lasting approximately 1 hour. The interviewers had a somewhat arrogant demeanor, which made me question the desirability of working with them, especially considering I have other options.
