I was referred by a friend of mine. They send me a mail to set up an interview. I was interviewed for GPS test engineer phone. The interview was easy. The interviewer asked some basic questions regarding telecommunications.After 2 weeks I got a mail from my interviewer that as the project he interviewed me for is on hold he is going forward my resume for other. After few days I got another mail for an interview. This interview was also easy. Questions regarding modulation technique, frequency band , difference between different cellular systems.
