I applied online. The process took 4 weeks. I interviewed at Spinofix (Irvine, CA) in May 2012
Interview
The first interview was based on my resume. They asked a lot of questions about my senior design project and mechanical engineering education since I didn't have any prior experience. It was about a 45 minute interview. The second and final one was to get to know the other interns. In the end, there was a brief Solidworks quiz to test how much you knew.
