Hello guys, Preparing for a system design interview is one of the toughest challenges for software engineers. Unlike coding interviews, where the solutions are often precise and testable, system design is open-ended. You’re asked to design platforms like WhatsApp, Twitter, Spotify, URL shortener, or payment systems, and the evaluation is based on your ability to make trade-offs, structure scalable architectures, and communicate clearly. This is all easier said then done and most of the candidate froze when asked to design a real world system on interview.
When I started my preparation journey, I quickly realized two things:
-
Concepts and visuals matter – I needed a way to deeply understand distributed systems, caching, load balancing, consistency, and other fundamentals.
-
Practice matters even more – It wasn’t enough to read; I had to apply concepts to real-world problems and practice under interview-like conditions.
That’s when I discovered the power of combining ByteByteGo with Codemia.io—a combination that turned out to be the secret weapon in cracking my 2025 system design interviews.
