They give me some classes and asked me to implement a method for one of the classes based on data structures. Then asked me one question about a given code using mutexes, I was told to find a bug or a problem in a given code. The interviewer wasn't interested about my previous work, about my projects even though I came with some years of experience . He was too cold, and not interested in anything I talked about.
