Behavioral and programming background questions at phone screen. Five in-person interviews in SF. Questions about regular expressions, data sorting, irrelevant 'math' problems, merge sort. After interview was called over the phone to interview in another division. Asked a dynamic programming question; but I doubt the interviewer knew it was a dynamic programming problem rather than simply a 'well-known' algorithm. Too much 'coding' and parroting out answers to well-known problems; little to no original problem-solving.
