I applied through a recruiter. The process took 1+ week. I interviewed at Zenefits (San Francisco, CA) in Oct 2015
Interview
They didn't even want to waste time on a phone screen with me...
So they emailed me and left me 2 * 4h assignments(pick one of two).
However, their uncleared requirements and strict feedback make me feel they don't want to hire any one in the beginning.
I totally agree with some people's neg review on this page.
