Vantaggi
Some really bright and passionate people working there.
IMVU is a pretty neat product and fun to work with.
As developers, we were allowed (and even encouraged) to interact with our users directly, so there was a very tight feedback loop for any new feature we introduce.
Svantaggi
Upper management took some huge risks on products nobody was really asking for, and when they didn't pan out, they weren't exactly straightforward about the status of the company. They kept laying off people in waves, always telling us it'll be the last time, only to do another layoff a few months later.
Some of the code you work with is quite outdated and difficult to work with using modern tooling.
There was also this weird obsession with doing everything in-house; if you wanted to add some open-source library there was a whole process you had to go through that involved multiple levels of management. Didn't matter if it was MIT-licensed or even public domain.
