Interview Question

Software Engineer Interview Menlo Park, CA

I expected a tirade of technical questions. The unexpected

  part was that the interview was both ways: they interviewed me, I interviewed them. Most parts were more like brainstorming session than exams. The most difficult question was when a guy showed me a gdb stack trace of the threads within a process which hung. It was an facebook internal application, so I had no previous knowledge of that application. The question was what went wrong. Luckily, it was a clear situation where all threads were waiting for a blocked thread.
