I applied through the university job fair and they scheduled a phone interview with me after two weeks. Yahoo's interview process is kind of slow; you have to push them all the time, otherwise you have to wait.

The interview was about one hour, and the questions were normal. First, the interviewer asked several C++ language basic questions, then about my resume. After that, there were three coding questions.

The interviewer was nice and helpful. He always gave some hints about the problems and kindly waited for my feedback. Normally, the interview should be 45 minutes, but mine was about one hour.
