Pros
Freedom to pursue projects that help players, even if they fall outside the scope of what would be considered your normal day-to-day duties. It's legitimately a company formed by gamers, consisting of gamers, for gamers. This shows through every aspect of Riot culture. If you're a gamer, you'll feel right at home. Benefits are great. Feedback is actually responded to. When we said 10 days of PTO wasn't enough, we got unlimited. When players let us know we're making a decision that isn't player focused, we respond and fix it. We don't always make the right choices initially, but we are quick to apologize and make it right.
Kontras
If you're not a gamer, you'll probably feel very overwhelmed by most aspects of Riot culture. It's very fast paced, lots of young people, and while outliers do exist they're few and far between. We still struggle with our own growth. We often find parts of our infrastructure that are incapable of scaling with our headcount. This leads to processes and systems being built, then quickly needing to be revised/scrapped for new ones.
