I applied through an employee referral. The process took 3 weeks. I interviewed at Analog Devices (Cambridge, MA) in June 2011
Interview
There was an initial 30-minute phone screen. Then there had an on-site interview. It started with a presentation in front of about 8 staff researchers. The style was very interactive, and they asked many questions (both to me and each other!). The presentation was followed by 3 interviews with 1 or 2 interviewers in each interview.
Interview questions [1]
Question 1
They asked about projects I had mentioned on my resume and asked me to explain them in great detail. Their other questions sprang from comments I made in my explanations.
