Had a phone call with the manager and was asked about my projects and work experience. Was then asked to come on site the following week. The on site interview was pretty straightforward and I got to meet everyone I'd be working with. Was offered the job after 2 weeks of the interview.

First, there is a phone interview with an HR person. Then, there's a virtual interview with Hiring Manager and Director of Engineering for the site. That's as far as I got, but I believe there is a panel interview after that. The Hiring Manager was fine, but the Director was really rude. It felt like he made up in his mind that I was exaggerating my experience and started nitpicking every little detail. He was also pompous and went on and on about how he used work at [insert prestigious company] and conduct interviews there.
