I applied online. The process took 2 weeks. I interviewed at Gusto (San Francisco, CA) in July 2015
Interview
The interview process was thorough but fun. After the in-depth analytical take home test I got to meet the entire team and have some one on one time with each of them (5 people at the time). A few situational case-type questions were asked which were challenging but interesting to think about and try and tackle.
