Horrible and hard to re think again, tough question and hifty environment. Let me explain how it started from,I applied online on the company website. About a week later, I got an email to schedule two back-to-back phone interviews in < a week. Second one was rescheduled last minute to next week. Both phone interviewers went very smoothly and the interviewers were very polite and easy to speak with. Each were an hour in length, with maybe the first 10-15 minutes of resume questions, background, etc., then it quickly became technical. I coded in a shared Google Doc for both. The first interviewer asked for whatever language (I chose C++), but the second one insisted on Python (which I was happy to oblige, it's actually my favorite to hack in). I had those two on my resume, so I assume they were probing me to see if I was lying. They will not ask you anything not on your resume and conversely, don't lie/exaggerate as if one of the largest tech. companies doesn't encounter that on a daily basis!
