How to start in procurement industry

I am interested in beginning a career in the procurement industry. I have a BA in political science and I'm currently getting an MSc in economic governance. How can I get an internship (and eventually a full-time job) at a procurement company? More specifically, as someone who's background is not very relevant, what hard skills do I have to teach myself to make myself as competitive as possible? Any helpful advice would be appreciated. Thank you.
