A complete guide to transition from service to product-based tech: DSA, system design, resume tips & mock interviews.
Switching from a service-based IT company to a product-based tech giant 🏢 might seem daunting, but it's entirely achievable with the right roadmap. If you're wondering how to make that leap, here's a practical guide to help you:
👣 Step-by-Step Roadmap to Transition
1️⃣ Master the Fundamentals: Focus on Problem-Solving (DSA First)
Master Data Structures and Algorithms (DSA)—they are foundational.
Platforms like LeetCode, HackerRank, and CodeChef are great starting points. Gradually progress from basics (arrays, stacks) to advanced concepts (graphs, DP).
2️⃣ Build a Strong Foundation: System Design is Crucial for Senior Roles
For roles like SDE II or III, System Design is non-negotiable. Learn real-world scalability concepts such as caching, distributed systems, and load balancing. Use resources like Grokking the System Design Interview.
3️⃣ Network Your Way to the Top: Strengthen Core Computer Science Fundamentals Revise concepts in OS, databases, networking, and object-oriented programming. These are frequently tested in product company interviews.
4️⃣ Ace the Interview: Highlight a Product-Engineer Mindset
Focus on the "why" and "how" of your work in past projects. Showcase your impact on scalability, performance, or user experience.
