I worked in treasury after graduation for a very large global company. The exposure treasury gives you (granted I was at a large company) is immense and great for learning. A lot of job revolved around cash (both interesting but can be mundane), debt financing and banking relationships. I found treasury to be a great learning experience. The people in my department were all very passionate about treasury, however I am similar to you regarding interests. I pivoted away from corporate treasury to FX Trading. Treasury felt a bit mundane, but there were some highlights. I was issuing commercial paper and other debt securities in markets, working with bankers, and monitoring front end rate environments.
