It was a very relaxed, phone interview with my potential supervisor. Basic questions about how i work best and why I chose engineering. He told me a bit about the project he wanted me to work on and basically offered me the job if I was willing to take the spring and summer off to work there.

I applied for the position through NASA's OSSI web site for students seeking summer employment. 5 days later I received an interview from an internship coordinator stating that I was being identified as a summer candidate for the specific project to which I'd applied. From there, a phone interview was scheduled for a few weeks later. The interview itself was quite easy. It had a few technical questions mostly covering entry level chemistry and materials science principles. A few months later I heard back that I was no longer being considered for the position.
