I applied for an entry-level (college grad) systems engineer I position. The hiring process for me consisted of two phone interviews and one on-site interview. The first phone interview was with the hiring manager -- pretty straightforward, just asking about my resume, background, interests, previous internship experience. He explained the kind of work I would be doing in the specific department and answered any questions I had. The second phone interview was with a senior engineer, and she focused more on gauging my interest/relevant experience for the job. I think she wanted to determine if I would be a good fit in the department. The on-site interview was with the two of them and an additional senior engineer. It was also very straightforward -- they asked what I did during my internships, what I learned, any challenges I faced, what classes I enjoyed most, and what I'm interested in. Not really any technical/STAR related questions. They also provided lots of time for me to ask questions (which I wish I prepared better for). I heard back in a couple days.

Was introduced as behavioral but was fairly technical. Asked a few technical questions about subjects of your choice. Discussed past experiences from my resume and what I would do in other technical scenarios.
