I applied online. The process took 2 weeks. I interviewed at Box (Los Altos, CA) in May 2015
Interview
The interview process was very in-depth. The process consisted of an initial interview with the recruiter and then a 1-on-1 phone interview with a person currently in the position. After that, the on-site process happens with an interview with several people.
