Microsoft Software Developer interview questions

A recruiter contacted me in august through Linkedin. I give him my CV, and around October I mantained a phone interview with a different recrutiter. This phone interview was focused on reviewing my CV, past projects, and questions about common programming issues such as recursivity. After this interview, I went to the last interview in Warsaw (Poland). In there, I mantained 5 different interviews with SW Engineers from Redmond during the morning. Each interviewer presents you with a programming problem (Data structures, recursivity, etc.) to be solved in a white board for 45min-1h

Contacted by a recruiter. Went on a hiring event. The interviewers insisted on using Java for coding and I was told that those who can't code in C++ or Java are weak software engineers.
