Pros
Riot Games believes in the talent that they let through their door by empowering them to pursue what they are passionate about. They encourage you to find a project that aligns with your career aspirations and adds value to our players. While I've heard this at previous points in my career, I have never worked at a company that truly put this into practice. They trust that every Rioter is highly competent and capable and allow them the freedom to take on short term productivity losses for long term development gains.
Cons
While embracing this entrepreneurial culture was energizing for myself, I can empathize with personalities who do not like having to find their own opportunities. Riot is a very unique place to work and it requires a person to be very self-aware of whether or not they are truly happy working in an environment like this. Riot does recognize this and provides candidates and new Rioters an opportunity to get a taste of the culture and see if it is a fit for them. The difficulty lies in whether or not an individual can make an accurate evaluation in a timely fashion without being distracted by the fun, exciting, and playful nature that is working at Riot.
