Phone screening and then multiple rounds with tech leads and managers. It was a horrible experience. They expect you to answer in a school essay pattern. It was one of the most unpleasant experiences. They would ask you to tell about any subject that you like and would grill you on that. They did not ask me much about my work. I said, "I can't remember stuff I don't use on a daily basis. I can tell what it is, but I cannot explain completely." They did not like that.

I interviewed with NSN (Nokia Solutions Networks). They expect you to give textbook answers and detailed answers. They asked me about the CSMA/CD protocol, which is very theoretical, though I told them that I don't use these at work.
