I think it's pretty common for a few reasons. If you're in big tech and love your job and know you're in a position where nobody else does it as well as you, you might see a career jump as your opportunity to get "rehired" into a higher level. This is very common with companies competing for talent in the same locations. I also think from the expectations perspective, some people don't know how good they have it until they join another company. This can be eye opening and you want what you once had. Lastly, for smaller companies, this is very common. There's something about smaller talent pools where your "deal" can be negotiated better than most big tech ones.
