I applied online. I interviewed at NASA (Huntsville, AL) in Mar 2015
Interview
Phone interview at first. Then got an email confirmation that I received the position. Didn't have an in person interview. When I arrived my first day, I met my mentor and we went through areas that I would most like to work in. We established that and the mentor set me on track for a successful Summer full of valuable experience.
I applied online. The process took 3 weeks. I interviewed at NASA in Apr 2016
Interview
Contacted a couple weeks after application. He talked about NASA a little bit and the types of work that was typically done during the internship. He then asked me some basic questions about myself and why I wanted to intern at NASA. Interview was straightforward with roughly 50/50 behavioral technical questions.
