My recommendation would be to call or visit your local pharmacy and ask to speak to the head pharmacist. Explain your desire to seek employment in that industry and ask if there is a good time that you could come in and speak to him/her about your questions and to get more information on the required training, a day-in-the-life, and the practical aspects of the day-to-day operations, roles and responsibilities, as well as any available career paths. Generally, people that are passionate about what they do are very willing to share.
You can certainly find a lot of information online - and the internet can be a good or bad teacher. Expanding the scope to have conversations with folks that are currently working in that field should prove really helpful!
Visiting several pharmacies (corporately owned, privately owned, those that specialize in compounding, etc.) would give you a broader understanding. Knowledge is power and can help you decide if this is the path you want to start on, as well as where it could lead.
All the very best to you in your future!
