LinkedIn Software Engineer interview questions

Applied on Company website. Contacted by HR, scheduled for technical screen. Online technical screen using a collaborative editing tool. Second technical screen by phone, no on line editing. Scheduled for 5 hour on site. senior manager for position and I had short chat about company culture, then got lunch. Then 4 sets of technical interviews with one or two people asking me questions. Culture was very exciting to me - the people seemed very enthusiastic about the company and that they would be solving interesting problems that would make a difference in people's lives.

First I went through a phone interview where they ask me the most basic questions, like what am I working on, what is my strength, ect. Second interview was a more technical phone interview where they ask me to write some class definition online using any programming language I prefer.
