For me it's what company does - does it do something useful enough, meaningful for people - and how the team in the company approaches reaching goals - do people in the company have a good, healthy, positive dynamic and attitude. Salary range is more a function of the market (yes, there are companies which seem to under- or even overpay), tech stack is changeable if needed, team size's flexible - if it's too big, it splits into parts. The most annoying thing... is that you often don't know what was not good from the company standpoint.
