What we care about
  • Solve for the customer first: You build what customers want. You think about what is right for customers, not what is easiest for you
  • Demonstrate mastery of honey badgery: You make ambitious goals. Then execute…no matter what stands in the way. When knocked down, you get up
  • Take on challenges willingly and can be trusted to execute: You can be trusted to get things done right the first time quickly. You hit your deadlines
  • You’re like us: You smile a lot, think work is fun and don’t take yourself too seriously. You measure yourself against the best and believe feedback is the breakfast of champions. You follow the golden rule.
  • You’re remarkable: People naturally talk about how awesome you are. If we can’t find someone who raves about you then it’s unlikely we will too.
