Career Advice for a New Grad

Hi everyone! I posted this on r/big4 but thought id ask here as well. I recently graduated in June of this year with a Business Information Systems degree and have been on the job hunt. Unfortunately during my time at college I was unable to land an internship. Obviously because of that my job hunt has been difficult because I have to leverage my projects/technical skills rather than work experience because my work experience is not related to major whatsoever. I wanted to ask what would be the best course of action for me? I want to land a big4 job but I know that I’m probably going to be blown out of the water compared to other applicants. Any advice would be great.
