It was a day-long interview process. The day was split into a tour of the company building and a white-boarding session. White-boarding session was technical. People were friendly but the technical questions were hard. They provided lunch.

Applied on company's website. After an initial phone interview, I interviewed on site. It took all day. People were very friendly and gave me a tour of the building. Then we had a white-boarding session with communication system questions. Transmitter and receiver design questions were asked.
