Employee referral. Phone screen interview with a product manager from silicon valley office. 45min scheduled interview that only lasted 30mins. The interviewer was not engaged at all. Very curt and quite dismissive and interrupting manner. e.g. Q:"Tell me a bit about yourself". A: "Well, I started off in a silicon valley start-up" Q: (Interupts) "I don't want to hear anything from your CV, assume I've read it all" A: ???! Be prepared for: 1) Market sizing for some google product 2) A new google product, improvement -- process for designing it Within 5minutes of hanging up HR had already written to me saying I was not progressing. I'm guessing the interviewer had typed up the feedback while he was on the call with me. Good luck and keep your cool, you can expect a wide variety of personalities and people -- it is Google after all.
