While the experience varies from job type to job type, I would generally advise you to look for an internship of some sort. It can be paid or unpaid, but try to look for something in the field you want to study. If you can't find a job in your field, any job will give you experience that you can use on a resume for jobs in your career.
If the job hunt just doesn't produce any results for you, volunteering somewhere in your intended field of study can give you great experiences as well.
Good luck on your job search!
