A recruiter contacted me and set up interview appointments. I got 3 interviews via phone from field test engineers (as they claimed). One from Australia, one from Japan and the other from Seoul, as I am living in Japan. Two phone calls came on time as the schedule, however, on phone call from Seoul Korea was delay, for 2 times without notification. The recruiter helped to set up interview call again. Overall, the questions are on parameters of LTE system. That's. If you are working on it, you can give answer correctly without thinking, if you don't, it is difficult to recall those parameters.

The process was pretty smooth and well communicated with flexibility in timings to schedule. The overall experience was a good learning experience. The interviewer was very helpful as well as he kept sharing knowledge throughout the interview process
