I applied through college or university. The process took 2 weeks. I interviewed at MuleSoft (San Francisco, CA) in Feb 2015
Interview
It was pretty fast and went smoothly. The recruiter did a great job keeping me informed about the process. There was a coding challenge and I got a super day right after that. The super day was 4 back to back interviews with senior engineers. I did it over Skype because I couldn't make it to their office.
