I was contacted through email about a phone interview, and a skype session was created for the interview (to do real time coding). The interviewer was friendly and made me feel comfortable. He started by asking me questions about my resume and the projects that I have done, and my internship experiences. He then asked me technical questions based on Networking protocols, Operating Systems and C programming.

Interview
They invited me for the phone interview. I was asked about my master thesis and bachelor thesis. Interview was good. Though I felt explaining some one your thesis on phone is not a good idea, as it is highly possible that other person may not understand exactly the thesis work. Even though I answered almost all questions confidently, the interview was surprisingly short - 25 minutes only.
