> Do people really not understand that companies don't care one whit about your personality?

When I worked at the original incarnation of HBO Max our #1 hiring criteria was "not an asshole".

When I joined MSFT out of college, they were big on hiring for future potential.

In any large company you're going to be reorged to a brand new project within a couple years of joining, so being flexible and capable of learning quickly is of paramount importance.
