I applied through college or university. The process took 1 day. I interviewed at Bose (Framingham, MA) in Mar 2014
Interview
There was a 1 hour long call with discussion about previous work, interest and right off the bat technical questions on circuits and engineering approaches. Then I went to the offices and talked to 4 different engineers who asked me 80% technical questions.
Interview questions [1]
Question 1
They had me solve a spring-damper system, they had me draw active and passive filters and there were questions on how to approach certain engineering problems.
