@hackproduct9: I’ve interviewed 400+ candidates across coding, system design, and data modeling. Here’s what I’ve learned: Most candidates don’t lose because they’re not smart enough. They lose because they’re preparing from 10 different places. One SQL platform. One coding platform. Three YouTube channels. A system design course. Random blog posts. Hundreds of bookmarks. And somehow, most of it teaches the same boilerplate content. The same employee-manager SQL questions. The same textbook system designs. The same interview advice recycled over and over again. Real interviews are different. You need to solve business problems. You need to reason through tradeoffs. You need to think like an engineer, not a memorization machine. That’s why I built HackProduct. One place to practice coding, SQL, data modeling, system design, AI fluency, and product thinking using realistic interview scenarios. Stop collecting resources.
