To determine if someone is a “cultural fit” at Skillshare, we created a set of core values as a team (during one of our retreats), and created interview questions for each one of our values. For example, ”Be Curious. Stay Passionate” was one of our key values, so we ask all candidates during the interview process, “what are you passionate about?” to get a better understanding of their passions for our mission and outside of work. This allows us to determine whether they are a culture fit or not based on our values and not on whether we can grab a beer with the person.
Lastly, we have an overall criteria of traits we look for when build out our team, which revolves around ambition/drive, curiosity/passion, and humbleness. We also look for “black swans” that have done something remarkable in their lives that make them stand out. For example, one of our recent hires was an Eagle Scout and another was ranked as one of top 100 piano players in the country.
