I applied through an employee referral. The process took 1 day. I interviewed at Dropbox (San Francisco, CA) in Feb 2018
Interview
5 mins of self introduction and asked about finding duplicate files. Asked how to resolve the conflict problem without looking at the content of files. Describe how MD5 works. Worked it out with 2 hints but was told not moving forward to the next round.
