Backend System Design Mock Interview

Santosh Yadav

Senior Software Engineer at Uber

Over 11 years, I've built scalable products used by millions - leading initiatives, conducting technical interviews, and mentoring 1,000+ engineers preparing for product-based roles. I've been through 150+ interviews across frontend and full-stack loops. I know what top companies evaluate beyond coding: architecture choices, trade-offs, communication, and engineering judgment. Today, I'm also building AI solutions and AI agent workflows — and I bring that same first-principles mindset into mentorship: clarity over shortcuts, systems over memorization. What you can expect: • Personalized roadmap — Frontend, Backend, or Full Stack • System Design sessions (LLD + HLD) with real-world trade-offs • DSA & mock interviews with actionable feedback • Resume & LinkedIn review for product-company hiring • Structured prep plan + curated learning resources • Guidance on moving from service-based to product-based companies My goal isn't just to help you clear interviews — it's to help you build strong engineering fundamentals and long-term career confidence. Targeting MAANG+, high-growth startups, or top product companies? I'll help you prepare with a focused, practical approach.
