BAE Systems USA Software Developer interview questions

Non technical, and brief. No studying required as no real software questions were asked. Past experience and known languages were inquired but exact match to company need was not necessary as they only needed general knowledge.

I had the first round interview at a career fair for a conference. The interview was brief (~30 minutes) and easy with 2 interviewers. It involved behavioral questions and general things about my resume. The interviewers also went through some brochures of general information about the company, including the various new-grad programs. They then asked for preference in location and told me that I'd be contacted to set up a second round on site interview. HR reached out to me for a second round in about a week. Although I had asked about expectations of the interview, I did not receive a reply. The onsite interview was about 3.5 hours. First half hour was a general info session where they gave a presentation about the company and a "group interview" (all the interviewees and interviewers in the same room). They asked more resume questions but it was a bit awkward since it felt competitive with all the interviewees answering at the same time. The rest of the time were split among 3 different sessions with different interviewers (just myself and around 1-2 interviewer per session). These sessions were purely technical with OOP and data structures questions, needing to whiteboard and write pseudo-code. The questions aren't too hard if you've done coding interview practices, but it was quite intense and felt very long. Received an offer about a week later and was told that I would have to go through another interview if interested in joining the rotational program, but I did not go through with it.
