I applied through university. I interviewed at DMC (Fort Collins, CO) in Oct 2014
Interview
I participated in two interview steps - an on-campus interview at my university and then a phone/online interview. I believe there would have been one final interview step at their office had I been selected past the second step. The first interview was basically an IQ test, where I answered brain-teaser questions to one of their engineers. The second interview required me to answer engineering questions on my computer.
The process took 1 week. I interviewed at DMC (Houston, TX) in May 2018
Interview
I had a phone interview with them. There were 2 parts of the interview. The first part was behavior questions and the second part was technical questions on the scribblar website. I used Text option to fill out my answers. There were 3 questions for the technical part.

Interview
The interview started a bit late. A panel of three male engineers asked me questions about my resume and then gave me a few written assessments and watched me take them. The interview was more conversational rather than an interrogation.
