A lot of it is company culture. Does the boss agree to unreasonable deadlines with the client or marketing team? How many people on the team are jerks? How many are lazy or unmotivated? Is there enough respect for the boss?

Is the company fair? Do they prevent you from taking sick leave when you are sick? Do they pay a little less than they hinted? Do they compensate you for travel time if the office is in an inaccessible area?

Is the company an exciting place? Do you feel good, feel proud of being part of the company? Does the company do things that you're embarrassed of? Are the projects meaningful?
