It's not a number - each person's history is unique so its a lot more nuanced than that.

When hiring we're looking for someone who'll fit, someone who will add to the whole. Hiring people is expensive, each new person is a lot of time invested. We want to feel like you'll want to stay for a while.

Getting that feeling is hard, and of course there are no guarantees in life, but we don't treat people as fungible. You are you, and we can't just go down to the supermarket and replace you.

History is no predictor of the future, but it can be a signal.
