It started with an initial screening by the hiring manager, Then the final stage was three back-to-back sessions of 45 minutes long with the hiring manager and two members of the team. In the final round, first session was more of technical questions on modern control theory and also about my background and the research works I have done during my PhD. The second session was all about C++ coding. No leetcode type questions. It was more focused on evaluating of my understanding of C++ coding. The third session, to be honest, was a disaster. The interviewer was very aggressive and impolite. He asked some basic questions and I answered all of them. But, it was obvious that with his biased attitude, I will be rejected finally. It is really disappointing that they have such a jerk in their team.
