Recently interviewed at DBX, got rejected; some of the feedback was that I didn't give a good multi-threaded solution to the web crawler problem. Somewhat puzzled since I thought I did ok on that part (the rest of the feedback was pretty-much in line with my own evaluation). Can someone (Dropboxer or not) point me to a valid solution for this problem, still bothers me = ). Thanks.
Depends on the question and the level, bar can be different. What answer did you give and I will tell you where you were missing :)
