The process was very straightforward, and one of the best I've gone through. There were 4 rounds total. The first was a pretty standard 30 minute in-person chat with two members of the Dropbox team (one senior and one currently in the DRP). After passing this round, I was sent a questionnaire to complete. The questionnaire contained questions about how I have used Dropbox, my work background, how I would respond to a few customer service inquiries, and what kind of metrics I would use to measure user engagement. After passing the questionnaire round, I was flown out to San Francisco for a day of interviews with different people in the company. During that day, I had 6 interviews total, each with 2 different people. Some of them were more casual than others, with one being a tour of the office (during which I was sat down and casually interviewed about my hobbies and interests). All in all, it was a pretty great experience, and even though I was not offered the position, I had a good time and left with a good impression of the company as a whole.
