Applied for this position online. Received on-site interview within a week without phone screening. I was invited to directly approach the interviewers without going through the HR building. The interview schedule included six engineers and lasted for almost a day. The interviewers were knowledgeable about their material. The interviews were mostly technical with short inquiries on work-habits. The interview questions ranged from telecommunication theory, system-level protocol specifications, hardware block-diagram design, and software programming skills. All the questions were fundamental to the job. If you studied the basic theory from textbook, then passing the interview shouldn't be a problem.
The building was large and it was partitioned into individual small offices. The engineers were patient and rather proud of their work. The working hours were long and it looked like some engineers might be sleeping in their office just to save time. This is probably one reason why this company is so productive.
