60-Day Roadmap to Crack a Product Company Interview

Preparing for a product-based company interview while working a full-time job can feel overwhelming. There are so many things to study — DSA, system design, LLD, and behavioral questions. It’s easy to get lost without a clear plan. In this video, I share a simple 60-day roadmap to help you prepare in a structured way, without trying to learn everything at once. Here’s how I would divide those 60 days: *Days 1–30: DSA and LeetCode* Focus on LeetCode 75. Understand the patterns behind the problems instead of just memorizing solutions. *Days 31–40: Low-Level Design (LLD)* Work on object-oriented design, SOLID principles, design patterns, and common machine-coding problems. *Days 41–55: High-Level Design (HLD)* Learn the fundamentals of system design, including databases, caching, messaging systems, scalability, and distributed systems. *Days 56–60: Behavioral Interviews* Prepare stories about your projects, challenges, conflicts, failures, and leadership experiences. Knowing how to communicate your experience is just as important as technical preparation. This is the approach I would take if I had 60 days to prepare for product-based company interviews while continuing to work. You don't need to study for 8–10 hours every day. What matters is having a plan, staying consistent, and making the most of the time you have. What do you find most challenging about interview preparation: DSA, LLD, HLD, or behavioral rounds?
