Dropbox was known as a hard place to interview since 2014, the tech companies that had the hardest technical interviews are Quora, Palantir and Dropbox(honorable mention fog creek)(this was from a few years back so things may have changed). Just because the company makes it extremely difficult to get in does not mean the company is generally all around awesome or pays great or employs the greatest engineers. It optimizes for people who generally come straight out of an elite CS program with those learned concepts fresh in their mind, and for people who grind out on leetcode or who are great at interviewing. Of the three companies I mentioned above I would not work for any of them now.
