The interview process started in December 2015. I gave three phone interviews one with the Director of Engineering and the other two with principal engineers. Each interview lasted for about an 45 minuter to an hour. They asked me questions about projects on my resume, and also some techincal questions on digital logic design, concepts of CMOS design , critiquing circuits etc. Thee also asked me questions on scripting, RTL, etc. The interview was OK, I couldnt answer some questions.
