Applied for an internship. The first round interview was on-campus. I was asked to code a common simulation game that you may have heard of, and then to scale it for a million inputs. The interviewer was on his phone while I was programming and not very interested in me beyond the code.

I got a second phone interview two weeks later. The second interviewer was also quite distracted and didn't sound very interested in interviewing me. He asked a question that was floating around on Glassdoor. I hadn't seen the question before but managed to solve it pretty easily. He then changed it slightly, making it a lot harder. I quickly told him the solution to this, which he agreed on, and I proceeded to code a slightly inefficient solution. I think he was disappointed with my code and decided to ding me at this point.

The questions were similar to Google's, not impossible like others describe. They were quite manageable.

Overall, I got a negative impression from the engineers at Dropbox. I met two other engineers at their office a while back too. "Elitist" and "bro-culture" are words I associate with them. That said, they have some very smart people. I actually like Google Drive as a product better, so I'm not sure what they do with all that engineering horsepower.

Recruiters were great and responded quickly.

Second part of second interview.

Required knowledge of some arcane data structure to solve it efficiently.
