University work-study experience, unless this experience is related to the position of the unit you are applying for, don't write it on your resume. In fact, employers don't like the experience of work-study programs to make money during college. They prefer to hire people who can study and engage in social practice in a down-to-earth manner rather than make money in their spare time.
For example, if you sell home appliances through work-study programs, it will be no problem to apply for a home appliance company. But if you study chemical engineering and work part-time as a waiter in a restaurant, the employer will be very uncomfortable.
