First was contacted by an interviewer. He was friendly and asked some screening questions on C++ basics and multithreading. I passed the screening and went to the first round. This was taken by a staff engineer. I was told to interview myself and we started off with what is polymorphism. I was told to implement a virtual function example in some IDE of my choice, and then I was told to implement own vector using C++. I started with the basic implementation but I got stuck at implementing the copy constructor. She corrected me and at the end when I asked for the feedback she told me to brush up on the basics again. The review given to the recruiter was that I lacked the basics, despite answering and implementing majority of the questions. I think such because of such faulty feedback environment present, better to avoid this company.

Good.. 3 level process of interview. Need understanding of the expertise and interviews were conducted in time. Product base company so they expect to know their products with the technology level of expertise that you have
