Pros

• Strong executive leadership pointing the company in the right direction • Best culture I've experienced so far -- the people I work with are driven yet compassionate -- we are expected to work hard and smart for 8 hours a day, then go home • Competitive compensation and benefits • Working on a product that's well known and loved by many people • Building a product that I use on a daily basis is exciting

Cons

• Frequent reorganizations and process changes, not surprising for a fast-growing company but could be annoying • On certain teams, there's a lot of tribal knowledge that makes it difficult for a newcomer to start contributing right away • People can be too nice to the point where difficult topics are avoided
