Arm interview questions

Applied online. Got a phone interview at the end of November 2012 with a team lead. Got invited to a face-to-face interview in Trondheim at the beginning of December 2012. Got face-to-face interviews with more or less all the top-level managers and my future colleagues. Had to give a presentation of some of my previous work (unexpectedly!). A few days later had a phone interview with HR. Finally got an offer at the end of January 2013.

Questions on Microprocessor, OOPS, data Structures, OS. Interview was on campus and first round was online test(technical + aptitude). HR interview was very basic-asking about family and stuff.Results were declared in the spot.
