The interview started on time, and scheduling and all other arrangements were fine.
The interview itself was not particularly difficult; it presented a good problem to solve.
However, I believe the question could have been made clearer. While I understand that interviewers may deliberately omit certain edge cases to see if candidates ask clarifying questions, I felt this particular question was incomplete. It took some time to fully understand and clarify it, time that would have been better spent optimizing the algorithm.
The interviewer appeared to be quite young. I suggest Dropbox provide additional training for interviewers, perhaps through shadow interviews or mock training, to better prepare them for conducting interviews.
There was also a language barrier, as the interviewer was clearly not very comfortable with English during the interview.
Nothing too difficult.
Study algorithms and graphs well.
