Pros
There's been a lot of external talk about Pinterest not being engineering driven. That's completely false. The caliber of engineering talent that i've seen here is just beyond amazing. This shines in many ways, and I think unfortunately we've been so buttoned down building an amazing product, that we haven't had the time to go externally promote ourselves. Then again, I would describe the eng org, the way I would describe Ben - low-key, shy, but brilliant. As an engineer that has done pretty much everything from startups to big companies, I can say that there is no place else I'd rather work.
Cons
It's a startup. We work hard and often have to figure what works best. It sometimes takes a few rounds, but when we do it feels like its essential and natural extension of the culture.
