What kind job experience impresses University admissions officers?

Frankly, most university admissions officers aren’t terribly excited about job experience. To the degree that it has any meaning, something which leads to a better understanding of the field a student is going into (for example, a pre-med student doing work in a hospital, or a film major having worked on a film crew) might have a stronger impact, but it is not usually a major factor in admissions.

tutoring… working at an education facility or something similar. a place that encourages the arts.

they like volunteerism the best though

The closer it is to true altruism, the better.
