I applied through a recruiter. The process took 2 days. I interviewed at Analog Devices (Norwood, MA) in Oct 2013
Interview
First interview was over the phone. It was very technical. The second round was on-site and included 2 hours with my prospective boss. We met in the very nice and clean cafe. Then I met with two developers in their work space.
My prospective boss was very tentative about being honest about working at Analog. Their technology and process is very old.
The development space is horrible. The building is a very dark and depressing cubicle farm with almost no windows.
The process took 5 weeks. I interviewed at Analog Devices in Jan 2009
Interview
A systematic process, met the recruiter at a job fair, then got a call to come onsite. The onsite lasted all day and was pretty rigorous. It was also a nice way to get to know the people in the group that I was gonna be working.
