Asked a probability question, then proceeded to ask about C++ data structures, opening and closing files, and then made me code it up. Wasn't too difficult, I was just really nervous

Phone interview. 10 min. The interviewer is friendly and nice. The phone interview starts with an introduction to the whole interview process and asks me questions about C++ and Linux. The basic questions contain the Linux version, what I use for the Linux system, the C++ version, the compiler, and the features. My professional C++ development experience has been also discussed.
