KPMG Audit Graduate Scheme

Hi, I’ve done my Master’s in Marketing from the University of Liverpool. I am an international student and would require a sponsorship in future. I see KPMG only provides sponsorship in Tax, Audit and Tech. I did my undergrad in Law.

Will I still be suitable for the programme if I clear the assessments or KPMG hires only graduates from specific degrees?

I was reading about previous graduates in KPMG website and all of them had done economics for some reason.
