Pros: Great people, good work-life balance, good benefits.

Cons: It may be hard to grow if you're not on an important team.

Pros: Smart people and lots of hard problems.

Cons: Leadership was hit or miss.

Pros: Square is a technology company that sells a "real" product. Our many merchants depend on us to help them run and grow their businesses. When our merchants grow, we also grow with them. The incentives are perfectly aligned for us to help them do well. We don't need to sell ads based on their information, and we're not selling acorn points or whatever. I work with incredibly talented people who have a wide range of experiences. We have a lot of fun at work, but we get our work done. Since Square has such a broad spectrum of engineering work, from hardware, to firmware, to back-end services, to security, to infrastructure, to front-end (think Ember/JS/CS), to mobile (Android and iOS), there are so many opportunities to learn and to try new things.

Cons: It's taken us a while to get our product vision/roadmap in place, but I think we're now in a good place. We're not as extravagant with our perks as other, more cash-rich tech companies, and the (free) dinner can be a bit hit or miss. The company has almost doubled while I was here, but that's simply necessary for us to grow our business.
