Pros

*Well positioned company with an enormous opportunity * Generous benefits. And baristas on several floors making drinks to order. * Still a lot of work to be done (depending on your perspective, this could be a con, but it's fantastic for anyone wanting to grow their career)

Cons

* Hiring like crazy. This is kind of a pro but lots of new people figuring things out and a lot of system scaling stuff * They got rid of some of the prepackaged snacks in the microkitchen for bulk goods. * Overall this is a great company to work for, not much to complain about.

Pros

Beloved brand and product. Smart and professional colleagues. Positive culture. A chance to build something in a nascent product vertical. Personal development opportunities galore.

Cons

A bit too high on our own supply. Need to be hungrier.
