I applied through university. The process took 4 months. I interviewed at US Navy in Feb 2014
Interview
The process was pretty straightforward, just a phone conversation about the kind of work you want to do and what your are interested in. Then you get a call a couple of weeks later. It then takes a few months for them to process all the paperwork; this is the most frustrating part as you basically don't hear anything for a long period of time.
They ask a prewritten of high level questions and ask questions that is written on your resume. A couple of people were in there, only one did most of the talking.It was about an hour long. No coding
I applied in-person. The process took 1 day. I interviewed at US Navy in Feb 2019
Interview
Introduced myself at job fair. Scheduled an interview for the next day on campus. I was interviewed by hiring manager and one young engineer. I was asked only behavioral questions.
