Go slow. Search on YouTube
"company name business model"
"Company name business case study"
Watch minimum 3 videos per company per search.
This will give you more insights about that particular company and industry. No mba focuses on specific business. Mostly generic content is taught in mba.
If you get bored then you may go for banking sector, search for your bank name business model or sbi cards business model.
Banking is one unique sector where debt is crucial part, other such sector is infrastructure and power.
Edit - once you start searching and learning then you may find many paid courses, tips, telegram and what not. YouTube has everything, no need to go anywhere else and depend on anyone.
If you need some good video links, I can DM you.
