I applied online. The process took 1 day. I interviewed at SolPad (Mountain View, CA) in Jan 2016
Interview
I met with the group in a large conference room. They asked me questions about my background and specific questions about my portfolio. I was challenged to provide solutions to proposed problems. Its a great company, I don't know what they are doing but I am hopping to get a call back with an offer. I was surprised by the quality of the people who work there. They have a lot of technical expertise from a variety of industries, many moved from across the country to work here.
