The interview process was smooth and well organized.

The interviewer was professional, explained the expectations clearly, and gave time to discuss my approach before coding.

Interview
The process included several stages. The first interview was a 30-minute conversation with recruiting. The second interview was a one-hour technical interview focused mainly on technical questions related to the role. The final technical interview lasted around one hour and included several participants. During that session, I completed a small live coding exercise in C# focused on problem-solving and logic, followed by a system design exercise where I had to propose the architecture for a system. After that, they asked additional technical questions. The last stage was an in-person behavioral interview focused mainly on communication, experience, and culture fit.
