Interview
I was asked to broadly describe my research experience in my graduate program. I was then asked specific questions about my experience related to the internship requirements. This included my prior CFD work (which I explained in my resume) and my competence in heat transfer and fluid mechanics. The interview was over the phone, and lasted 30-45 minutes.

I applied online. The process took 4 weeks. I interviewed at Sandia National Laboratories in Mar 2017
Interview
Applied through their website. I was contacted by the hiring engineers through email. We setup a skype interview. The video interview lasted about 30-45 minutes. They asked about my interests and what I've done so far that qualified me for the position for half of the time. The other half were spent on what the purpose of the internship was about.
