Anybody here have experience with the human resource department of a business?

Hello, I am wondering how hard it will be to get a job. I am 48 years old and about to graduate from a state university with a bachelor's degree with a Political Science and English double major. I worked as a waiter 12 years ago but quit when I inherited a small amount of money so I could pressure my passion, which is writing. During those 12 years, I worked as a freelance writer, having short stories and a novel published. I went back to school 5 years ago. I plan to work as an intern somewhere next summer before I graduate to get recent work experience.

I am wondering how challenging it will be, with 1 being easy and 10 being difficult, to find a job being a 48-year-old college graduate with only freelance writing experience and an internship as work experience.

Thanks.
