Northrop Grumman interview questions

I applied online and was contacted a few weeks later. i had three telephone interviews the; first a general interview with a manager, then a technical interview with an engineer, and finally a conversation with the government customer with whom I'd be working. The in-person interview occurred two weeks later. It consisted of a series of 1-on-1 interviews which took all morning, followed by a lunch with the manager, and another quick interview after lunch. Nothing unexpected, we simply discussed the type of work I would be doing and how it tied into my previous experience. I understood there were other candidates for the job, and i was given a date on which a final decision would be made. Unfortunately, this was the last I ever heard from them, even when i tried to make contact later I didn't receive any response at all.

I applied on NGC's website and got a phone call about 2-3 weeks later. The hiring manager/head engineer asked me about my resume, previous design projects, and experience with FEA software. He asked if I was available the next day for an onsite interview. After I said yes, he told me I would need to give a 10 minute presentation on my previous design projects. Interview Day: I arrived and was escorted in by the hiring manager. I began with my presentation to 4 of NGC's engineers (including the hiring manager) which lasted much longer than 10 minutes because of a lot of questions. After the presentation, the hiring manager asked me several questions on theory. We covered stress-strain curves and beam theory. Then I interviewed separately with each of the engineers that I gave my presentation to. One guy asked mainly behavioral questions. Another went into depth about my resume and gave me a little quiz where I had to hand draw a 2D drawing on a simple 3D part and make sure it was properly labeled (hole callouts, dimensions, fully defined, etc.) At the end, I had some final words with the hiring manager and was done. I interviewed right before the holidays and was told I wouldn't hear back until the first week of January since most of the employees would be on vacation. I got an offer letter on jan 6, which was earlier than I exoected. I also didn't expect to get the job because I feel like my interview only went okay and not outstanding, and I don't have a lot of experience. But I think what I said at the end of the interview made an impact, which was "I've interviewed with other companies and they've all told me that i interview well but the selected candidate had more experience. I would just like to say that I'm the type of person that will spend extra hours to catch up and learn the skills I need to know on my own time. So like during this winter break, I'll YouTube videos on how to use the 3D CAD and FEA software without you asking me to and without getting paid." This was only my 3rd interview but the 1st interview where I had to make a presentation and was asked questions on basic engineering theory.
