Sent in a cover letter and resume through the website (Jobvite). Asked to fill out a detailed "questionnaire" that was a series of short answer exercises given prompts (mine was about 3 pages single-spaced and took hours of work and research), including responding to potential customers and a question about Dropbox for Business's three areas of focus in the coming year. Next invited to have a 30-minute phone interview.
Questions asked during phone interview: Why are you interested in this role/Dropbox?; [We were talking about my use of photos and Dropbox] What would be next step for Dropbox and photos?; Experience dealing with customers?; Do for fun?
