Met with current employee at Dropbox at a conference who encouraged me to apply based on my experience. Lots of positive energy about the company culture and how much they wanted someone with my skill set, so I connected with a recruiter to discuss next steps. From there, I received a technical screen "coding interview" for an hour. There's 10-15 minutes of introductions, talking about the position and then the interview revolves around a single programming question. I found it had very little relevance to the position I was applying for. They were clearly looking for a specific answer in order to move you on, and I did not come to the same answer they wanted in the time allotted. I got a curt, no-reply email later that night declining me. It was really odd, after all the attention they put into convincing me to interview to go completely cold. In general, I really dislike the approach Dropbox took here in looking for the exact answer they wanted. Evaluate the solution the candidate comes up with and discuss the pros and cons about it. Rarely in a work environment are you ever "alone" in coming up with a solution. Questions like "You have a system you believe is experiencing an issue, what steps do you take?" or "Given a current bottleneck, design a system that overcomes the limitations."
