Extremely unprofessional and rude. Due to the nature of work you must be a U.S. Citizen to enter the closed off portion of the G.A. campus. You do this by going to the "public" building of G.A. that isn't guarded and getting a name tag from the front desk. Then you head onto the guarded/gated building. Now, if you have an interviewer (or set of them) who isn't incompetent, are actually being interviewed at a time when the company is hiring (it's fun to know some people internally who later let you know that you were just bullied for no reason), and haven't been already rejected but just there to meet some status quo you'll be met at the gate at your interview time by your interviewer and escort around the facilities. You will then be brought to the equivalent of a tiny closet (If you are of any reasonable height you will be uncomfortably pushed up against the wall by the over sized table) for the programming technical interview, after you'll chat about what you've done with 2 extra people who enter the room, and maybe even get a tour and then your offer. Now if you're in the unfortunate position, you'll be held by the guard as no one will be there to escort you for your interview, you'll then wait 15 minutes wondering if this is a joke/part of the interview and try to connect with hiring staff who can try and figure out what's going on. Then you will be met with someone you were not aware of being part of the interview process, led to that same tiny room and asked to do the same programming technical. Now, some more information about that cramped room of my experience. Your screen is displayed on a projector, to make it easier to ask for help or what's going on possibly. But you will probably end up using it as your primary monitor as the main display monitor you use will blink every minute to a black screen for 5-10 seconds. You can ask if you can adjust it, or even ask if this is normal, and you might just be gas-lit into thinking there's no issue. It seems that the solutions will also be open in another note pad on the same computer you're on, or that was someone else's solution. They don't try to make a clean slate or comforting interview environment it seems. Anyways, after the technical 2 more interviewers come in to join in. And while maybe there intent was to really "dig deep" into what you have done and your resume, it comes off more as condescending bullying. You'll then be escorted out by one of the interviewer's interns, who may try to apologize for the brash and rude behavior. I understand that I was interviewing in an unfortunate time, a major down swing for many, but I was lucky enough to have many more interviews and even land a job quickly after this one in Oct/Nov 2022, but none of the other interviews were as (six letter expletive) up as General Atomic's. What amazes me even more is, this is not an unusual experience among many I know who interviewed there and those who currently work there.

Interview has two stages, a phone interview and an in-person interview. The phone interview was 90% technical questions about programming concepts (what does object oriented mean, what does an operating system do, what is a stack, etc). I did pretty well at that, so I was invited for the in-person, which had 5 other people: two fairly new employees in the position I was applying for, the guy who interviewed me on the phone, and two others. We did the usual stuff, asking questions, talking about my past experience, etc, then they had me design a simple system on the whiteboard, describing the features it would need to have and the fairly high-level implementation details. After that 4/5 people left, and I had to do an assessment (coding challenge type thing) in C, which went pretty poorly. I was using notepad to edit the code since I'm not that familiar with console editors like vim, but the main issue was that I needed to do one thing which I didn't know, nor had I ever done it before: converting a double into raw binary data. The person who was with me tried to help, but it didn't seem like she knew how to do that either, since the only method she suggested (using the shift '>>' operator) only works on integers. I also wasn't allowed to look up how to do this on the internet. Other than that one issue, the actual problem was pretty easy: I just had to take the given doubles, convert them into a very long binary string, and duplicate any substrings in it which were equal to some value (such as 0x5f), and output that. Because I couldn't do the problem without being able to convert doubles to binary, the person with me just asked me a few questions about how I would solve the problem, I wrote a note in the code file, and I left. I later heard that the reason they declined a job offer was because I scored too low on the assessment.
