I applied through college or university. I interviewed at Leidos
Interview
First what I got was a phone call technical interview and was said to find out what the results would be in two weeks. Just 5 questions, start as soon as the call starts. They were really nice.
I went to a conference and they looked at my resume and asked me several questions. Then they decided they would like to interview me. The interview process was fairly easy. They asked about the things I worked that dealt with coding.
I applied through a recruiter. I interviewed at Leidos
Interview
Phone interview, followed by in person. Standard questions, nothing specific. Wanted salary information before in person interview. The process was very quick and background check started as soon as I accepted the offer.
