First round of interview was over phone, a half an hour conversation with the group manager, then an on-site interview was promptly scheduled. On-site interview consisted of an hour long written test, followed by four one-on-one interviews with team members, with a lunch in the middle. Questions in the test varied from trivial (e.g., what's the difference between an array and a hash) to ones that clearly had no completely correct solution (e.g,, write a program that extracts all people's names from text). Each interviewer would then go over the test digging into one question or another.
