Pros

So many pros... a product that is truly innovative and making peoples working lives simpler, happier and more productive, fabulous office space, amazing food, massages... But, I am probably most impressed by how amazing the people are. Respect, courtesy, humbleness, collaboration, and great work ethic abound. I genuinely love coming in to work every day!

Cons

The timezone difference between Dublin and SF HQ (and other offices) can make connecting with our international colleagues quite challenging. But, generally there is a lot of understanding and flexibility surrounding this.

Pros

A brilliant working environment full of highly talented people.

Cons

None really. It's a very high growth company so there's constant change as we evolve, but I like that.

Pros

Tremendous company to work for. Leadership truly cares about the employee base. Hard work is recognized and rewarded.

Cons

Growing pains. The company has 3-4X in size over the last 2 years. Systems break when any group scales this quickly - but entrepreneurial spirit is encouraged
