My company was largely run on dropbox as a crucial piece of infrastructure for many years before my arrival. As of a couple months ago, it has been cut out of our production pipeline entirely, but for many years, if you saw a digital out-of-home ad in certain places, it only got there because someone had added a media file and schedule to a dropbox folder. Looking back on it, it's pretty wild how much of their business relied on dropbox working reliably. Thankfully, that's all gone now.
I'm a current employee in the FoC (just not StockX), and with more than a decade in software development, I am easily the least experienced on our team by several years.
I very nearly worked there in their engineering department, but once I got through the initial HR interview into the technical stuff, there were so many red flags that I got outta there as soon as I could.
A few higher level people who were all let go with me ended up going there, and having met up with them a few times, I've heard some absolute horror stories about everything ranging from dev workload, to security, to extremely unqualified devs being hired to fill seats.
I'm not surprised by this in the least, and frankly, I'm surprised it's not worse.
