I interviewed as an SE a while back. The hiring manager actually forgot about me. She eventually remembered after the recruiter tracked her down and then she randomly decided to just drop me. Eventually a different team picked me up and the hiring manager came back and asked me to be on her team again... definitely not.

The process was straightforward and involved a project and presentation. Interviewed with recruiter, hiring manager, sales team, and other solutions engineers. I was lucky to receive great communications and support from my recruiter.
