I have interviewed with BAE twice for entry-level roles. Just one interview each time, though you will likely talk to a recruiter beforehand over the phone or via email. Interview was normal, asking questions about your experience, some engineering fundamentals questions to test your problem solving skills. However, DO NOT expect a response from them if you do not get the job. They are terrible at providing feedback from interviews and it can be extremely frustrating. Seems like a good place to work otherwise!

First - Personal interview with your potential new manager, asked questions regarding general job history and background. Then about a week or two later had a panel interview with 3 execs/hiring manager, which entailed more detailed questions regarding previous job, followed by behavioral, and technical questions
