Interview was very straightforward and not technical at all. Mostly behavioral questions and relatively short, maybe 10 minutes. The interviewer did ask about what experience I had with programming languages, and how much. After the interviewer asks you questions, you are free to discuss whatever you want. The interviewer seemed pretty laid back and you could easily ask about salary, company culture, and workplace environment. The interviewer was very understanding that this position is an internship, and that learning was a big part of it so some of my shortcoming in the programming languages I didn't know and were used in the job was to be expected. Overall very friendly and nice.

I applied on Lockheed Martin's website, then received an email from their hiring manager inviting me to a company dinner and hiring event. I attended the dinner beforehand and chatted with fellow interviewees and current employees, and the next day attended the hiring event on the Lockheed Martin campus. It was an all day event with presentations, tours, and breakfast and lunch provided! Every employee I met was very knowledgeable and wonderfully nice!
