AppNexus Software Developer interview questions

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.
