Pros

An excellent product to work on, with a company that doesn't just value diversity but actually hires for it, and tons of opportunities to explore different areas of problem-solving at a rapidly growing company.

Cons

- The "nice" effect - some people shy away from giving honest, hard feedback, instead focusing on being perceived as 'nice' we're getting better, though. - The hiring process is a bit of a mess: from leveling to compensation ("we don't negotiate offers" - HA! Negotiate EVERYTHING, people), you'll have to negotiate the hiring waters carefully if you're lucky enough to be a part of this team.
