LinkedIn interview questions

Recently I have been interviewed with this company. I had high expectations but it seems interviewer was a fresher, on the first phone interview he started to ask theoretical questions like definitions of some term as I am fresh college graduate. I was astonished and got confused though I answered the data structures problems but I was sure I m not gonna go further with this company. I think they need to give some kind of training to their interviewer. And they should keep their ego on their desk before coming for interview. He may b amazing engineer but anytime any one can screw no matter how much good you are.

First round was behavioral and they just asked about how I got into CS and other standard questions about my interests. Second round was an hour long technical interview. Third round was two-one hour long interviews. And fourth was just talking with the team.
