Pros
Amazing perks and salary with the market (still below what is needed to live decently in London, but very few companies pay that well in this market). Good equipment and one of the most beautiful offices I've ever worked in. The Unity3D product is one of the best we have in the market, but my division (ads) it's facing some issues that certainly will be solved soon. Overall it's a place with very bright people.
Cons
They hired some people that have no fit with the company at all. We are supposed to help developers grow using our platform for app discovery. This means the whole team travels a lot and goes to events. A lot of social interaction. One of the new hires, that comes from the mobile advertising space, basically can't control himself on dating apps and with clients. And it is fine until it starts to impact business and morale in the office. We can overlook somebody that is unfit and not that bright, but not overlook this kinds of misconduct after what happened last year. We are losing revenue and while some women don't mind, others are putting our hard built reputation on the ground. Lots of office politics, hard to navigate if you come from a no-BS environment. Sometimes we hardly have stuff to do or it is extremely boring.
