Its tricky to use statistics for personal decisions. In general something might be correct but not for your specific subgroup. I know many people who changed for worse.

If you are in a bad position then change, but if you like the company and role, don’t take it for granted and think carefully.

This advice is consistent with the broad statistic if more than half of the sample is currently in “bad position”.

Since we are talking about BigTech, I can’t imagine to a first approximation any IC up to and including senior or a low level manager being at any BigTech company for a reason besides wanting to maximize their income via cash and RSUs.

Does anyone stay in the same position/team for more than two or three years even at the same company?
