We had a fellow just out of college walk in off the street, maybe 2015 or 2016. "I heard you guys do Clojure programming here, is that right?" We said yes. He said I'd like to interview. We interviewed him that week and hired him.

We were a small-ish startup and he had done his homework, showed interest, and could write code to our standards. He stayed for a year or two and then moved on.
