I was only interviewed over the phone by hiring manager + future supervisor before getting an offer a couple days later. I was asked basic questions about my resume, as well as my experience with specific skills and situations.
I applied through university. The process took 4 weeks. I interviewed at RTX (Marlborough, MA) in Mar 2019
