I applied online. The process took 3 months. I interviewed at Porifera (Hayward, CA) in Apr 2016
Interview
Got a call back, but person running the hiring process took a long time to respond. Actual interview was a panel and was mostly an interview for 'fit' as opposed to skills. Director of engineering asked some engineering brain teasers but otherwise just showed past projects.
Interview questions [1]
Question 1
How do you feel about going out into the shop and working with your hands?
