The interview process at this company involves multiple stages: Initially, I had an interview with HR to discuss my work experience and salary expectations. Following that, HR informed me about the subsequent interview stages: An English proficiency interview. A technical interview. A "project" interview. Finally, a client interview process, which may include additional interviews depending on the client. I progressed to the technical interview stage but unfortunately did not pass. The interviewer, who was from Europe, asked challenging questions related to .NET concepts, including the Common Language Runtime (CLR) and the garbage collector. He also delved into low-level topics such as memory management, including where large values are stored (heap or stack) and methods for freeing up object space, touching on concepts like destructors and the dispose method. Additionally, there were questions about asynchronous programming, where I was asked to apply async methods to solve a given problem. Unfortunately, I struggled with this aspect. Surprisingly, there were no questions about SOLID principles, object-oriented programming, or design patterns during the interview. Although I sensed I hadn't performed well, I didn't receive any feedback until I followed up with HR two weeks after the interview. Eventually, I received a generic rejection email.
