It depends on what area of biotech you want to pursue. There are majors in the health sciences (biology, chemistry, etc.) geared toward research and development, business geared toward working on the commercial side (marketing or sales), finance for the business side, human resources (to recruit, hire , develop talent), engineering (manufacturing), and/or supply chain management. The list goes on...
I would talk to your school guidance counselor or advisor about potential ways to narrow down your interests to best serve you in your educational pursuits. There are also free tools on the internet where you can take personality inventories to determine where the fit is based on how you are wired and what you enjoy and like to do. Be sure to search based on 'career' personality tests associated with your current education (high school, college, etc.)
Hope that helps,
