I’m the speaker in that video. Historically, on average, I’ve stayed at each of my employers for about 2 years. Google was a big exception, as I was there for almost 6 years, but partly that was because I had 3 fairly different roles during the time I was there.

So far, a month in, I’m loving working for Slack; it’s a great company, and an excellent group of people. So there’s every possibility that I’ll be there longer than 2 years!
