Switching every two years is a red flag for employers and is called out during hiring in many companies.
Every 3-4 years seems to indicate a better uptick in interest / offers in my experience. Otherwise the concern from many Hiring Managers is: I'm going to invest my time and effort (~6 mos) in training, and that will be lost very quickly.
In my view a promotion is every 3-4 years as well (although it can be faster) at the FAANG companies. If someone is able to get a promo, that is the best time to start looking. It establishes that the individual is on an upwards trajectory so it makes it easier to hire them and convince others if the company is committee based on hiring decisions.
