It was all technical and I cleared the written too. Technical round: In this round, they asked about my resume. Remember the things that you write only those things in resume, in which you are very well, else it will create problems for you. They asked first about myself, and then about my programming skills. They give me a problem to solve in C. They ask me about SQL commands (because I mentioned in resume) like difference between delete and truncate, left join with syntax, then some questions from OS and computer network. I also found out that they were taking my stress testing. They fired questions very rapidly. Don’t give up they will make you feel free environment if you will get nervous (at that time I was). HR round: In this round as usual they asked about personal question to starting with about yourself. They asked some IQ questions like which object with four points are at equidistance, draw three co-centric circle without pull-up your hand, they also asked question, if a bear is jump from 1 meter in …sec. what is the color of that bear. Answer is related to measuring gravity according to south and north pole, and I was confused at that time. They also asked the meaning of my name, I gave that answer.
