Most people apply to fintech companies 10, 20, 30 times and never hear back. I came from a Finance/BBA background — not a design school, not a CS degree. And I cracked a fintech KYC company in one interview. This isn't luck. It was preparation, the right resources, and thinking differently about how to learn. This list is everything I actually used — the books that rewired how I think, the tools I used daily, the courses that built my skill, and the resources that made me interview-ready. If you're a designer, a career switcher, or someone from a non-traditional background trying to break into fintech or tech — this list is for you. No fluff. No theory. Just what actually worked.
