I had a phone interview. The interview was tentatively scheduled through an email. I was supposed to get a confirmation of the schedule 2 days prior to the interview date but I did not get it till on the morning of the interview. I was kinda partly prepared for the interview because I thought I had more time since I did not get a confirmation. So, I would suggest that one has to be prepared (regardless of the confirmation from the staffing co-ordinator) when they receive an email or a call that their resume has been shortlisted for an interview. The interview was basically on the skills they require for the position. Since I am a new grad, most of the questions were about my course projects, my coursework and my work experience as a graduate research assistant, everything in detail. And then, he asked me questions on C, mostly 'Data Structures' (Linked Lists, Stack). He also asked me some basic questions on LTE like, What do u know about LTE, What are the channels in the LTE technology.
