The interview process was smooth and well organized.

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.
