Here are our Questions of Threes (of threes) for interviewing on culture and values. We resonate with the culture at Netflix (people over process), Amazon (disconfirm your own beliefs), Google (social safety net). We also regard Y-Combinator's Employee #1 series as a good model for hiring.

Candidates self-score from 1 to 10 on the 3x3x3 questions below; they add a few words to explain with specific examples or personal stories. We also practice singing our song “Teach the World to Sing In Perfect Harmony.”
