Pros
Wargaming is a booming business, and when it wants to throw money at a problem, it can throw a lot of money.
Cons
Every piece of technological infrastructure within the company is horribly mismanaged, by "owners" no one knows how to contact, in a configuration that isn't accessible to anyone, on hardware that can disappear at any moment. It's likely that a full day, each week, will be lost to a failure of X, Y, or Z critical backend. Every technology company has this problem in some severity, but Wargaming actively works against fixing it -- infrastructure ownership is tied directly to internal political power. A middle-manager will often sacrifice the reliability or quality of an important resource, and focus on his own fiefdom's pet project, instead. International communication problems also hold back internal development. A "team" may supposedly span the globe, but in reality only one office is in charge, and the rest are treated like untrusted offshore labor - their suggestions and issues ignored - and get blamed for the "real" team's mistakes. Wargaming's internal technology has problems that no engineer should have to deal with, and the people who can fix those problems refuse to do so.
