I'd been contacted by a recruiter. The first step was a phone interview where they asked why I'd like to work for them and about my previous experience. Second step was an online test (C++), pretty simple, regarding memory management and STD Library. Third step was a F2F interview in their headquarter; they asked to solve a few algorithm (pretty tough) and to design a data structure. In my opinion the main problem with the interviewer was that they didn't have a clear idea about what to ask and it seemed like it was their first interview (not good in asking the question).
