I applied through a recruiter. The process took 3 weeks. I interviewed at Penumbra (Alameda, CA) in Aug 2015
Interview
Surprised they wanted to interview without phone screen. Some were 20-30 minutes late. Some people didn't show up at all. Products seemed good, HR was nice, but sensed imbalance of power between management and workers though workers were too pc about it. That is how I knew. Not willing to pay market rate.

Question 1
generic interview questions they seemed to think were unique.
