You didn't say this, but to be clear for those who may have assumed it: 2 years median time of service != median employee quit after 2 years 2 years median time of service can be explained by lots of people quitting, or by lots of people being hired (and usually a mix of both). I've noticed at Google that some positions (like recruiting coordinator) seem to churn quickly, while others (like software engineer) churn much more slowly. I haven't seen many engineers quit in less than two years (and certainly not in 1.1, which is the median in the data you linked to)
