I submitted my resume at my university's career fair. Got an email within a week to schedule a call to talk about my resume. This call essentially was used to describe me the position and schedule a technical phone interview (very basic and general questions asked so far). I chose it to be a week later. The technical interview was broken into 4 parts: 1. Math 2. MATLAB 3. Programming concepts and C (or C++/Java if you choose) 4. Control Theory (or Signal Processing/Embedded Systems/Computer Science if you choose) If you've studied/used any of the above in undergrad, you just need to brush up on some basic concepts. Nothing too difficult. It's like a rapid fire set of questions.. generally fundamental in nature. Brush up on the basics! Interview lasted about an hour. Got through the technical interview, and got called for a "college day" to Natick, MA, where it's going to be a round of HR+manager+technical interviews (They were flexible as to when I could come visit. I chose 2 weeks later just because I was occupied in the period between). There are other applicants attending too, and you're told that you're not competing against them as there are enough seats for everybody!
