Roadmap that can help you ace the interviews

 Here's the roadmap that can help you ace the interviews

Month 1 - Master System Design Fundamentals

→ Load balancing, caching, databases, APls, microservices

→ Understand trade-offs: latency vs throughput, consistency vs availability

→ Study real systems: how Netflix scales, how Uber handles realtime data

Month 2 - Deep Dive into Distributed Systems

→ CAP theorem, eventual consistency, partitioning, replication

→ Learn how to design fault-tolerant systems

→ Study case studies: Google's infrastructure, Amazon's DynamoDB

Month 3 - Build Real Projects at Scale

→ Don't just solve LeetCode, build systems that handle scale → Build: rate limiter, URL shortener, chat system, notification service

→ Deploy them. Make them handle real traffic.

Month 4 - Learn Production Engineering Skills → Observability: logging, monitoring, tracing

→ Infrastructure as code, CI/CD pipelines

→ Incident response and debugging production systems

Month 5 - Mock System Design Interviews

→ Practice designing systems in 45 minutes

→ Explain trade-offs clearly

→ Get feedback from senior engineers or mentors

Month 6 - Polish Communication & Problem Solving

→ FDE interviews aren't just technical, they test how you think → Can you break down ambiguous problems?

→ Can you handle disagreement on architecture decisions?

Final Push - Build Your Portfolio

→ Document your system design projects

→ Write technical blogs explaining your architecture decisions

→ Show that you can think at scale, not just code

The difference between SDE & FDE

SDE: You write code that works

FDE: You design systems that scale to millions of users & don’t break.

That’s why FDE roles pay in crores not lakhs
