Painfully boring and lengthy phone call. This was not an interview, it was an interrogation. Seriously one of the most boring phone calls I've ever had. The hiring manager seemed like he'd never done an interview in his life.

One phone screen interview and 4 on-site interviews (coding, algorithm oriented & behavioral). Interviews were of average difficulty but dealt a lot with optimized algorithm oriented. Friendly visit to the office, stocked kitchens/cafeteria - Had a fun day interviewing!

It was a phone screen. I talked to a technical guy, who asked a few reasonable questions. He was polite and patient. I managed to answer the questions. There was also a coding part, which I screwed up -- made a few mistakes on the way. Not to sound like an excuse, but it is probably because it was my first time coding on a white board. The man was patient and helpful. Seems that it is no so bad, when you know how to approach it and usually they help you a bit, because it seems they are also human, not acting like robots. Maybe because of these mistakes I did not get to the next stage, but it is a good lesson for md too -- need to practice apparently.
