45 phone call. Mostly getting to know you, little bit on the technical side. This is the first step in their interview process. Next will be technical. Applied online and got a response within 2 weeks.

Got a phone interview about 1 month after I applied online. Basic questions on engineering. This was followed by an onsite interview. It was about 3 hours long, where 3 different had about an hour each to interview. Questions were in depth and detailed, some surprising. Midway through the interview there was lunch and a tour of the facilities.
