It was just a quick 30 minute interview about my experience and how it pertained to the positions. They also gauged my interest in the position and my knowledge of active optical systems.

I submitted an application online. Later I had a brief non-technical phone interview. Next they flew me out for an in person interview at Lincoln Labs. They told me that I should prepare a 30 minute talk on my research. When I arrived I met with HR and then with several people in the group with which I was interviewing. They were completely disorganized and did not seem prepared for me to give a talk. So they only had me talk to several people and I was done before lunch. This was awkward and frustrating given that I flew across the country for this interview for 3 hours of conversations that could have been done on the phone.
