Behavioral Technical Coding
The process started with an initial recruiter call. This was followed by a 30-minute technical screener focusing heavily on .NET knowledge, which felt quite dated. Then came an interview with the team lead and another senior engineer, characterized by a 'good cop/bad cop' dynamic. The senior engineer was notably arrogant and unpleasant. When it came to whiteboarding, I chose to leave. The plan was for at least three more stages after this.

Technical Coding Behavioral
The first interview involved translating a protocol from binary to a meaningful explanation using its definition, along with some basic C++ questions. I also had to discuss my previous experience and offer recommendations. The next interview was with the VP of R&D and HR, covering high-level technical topics and standard 'tell us about yourself' questions.
