“I had an excellent system design session with Dejan today. He broke down the core principles of approaching system design interviews in a way that clicked for me. We discussed how to structure answers under time pressure, what common pitfalls to avoid, and how to prioritize clarity over complexity.
Dejan also helped me identify which areas I should focus on next. We even dug into how one might architect something like YouTube, which made the concepts feel much more real and applicable.
He’s clearly deeply knowledgeable, but just as importantly, he knows how to explain things in a digestible and actionable way. Highly recommended if you’re serious about leveling up your system design skills.“
