HR emailed me first to schedule a Skype interview. My Skype interview took about 40 minutes. The interviewer is very polite. Just some basic problems mentioned on glassdoor. The low-pass and high-pass RC filter, the MUX.

The Interview process was pleasant. I applied through Company webpage and got a mail for a Phone screening within 2 days. The phone Interview typically consisted of questions others have already posted on the glassdoor. But don't expect the same questions, there will be tweaks in them. So analyze each question critically and prepare for the interview.
