Mock Interview (System Design - HLD) with GOPAL JAISWAL

Hi, I’m Gopal Jaiswal — Senior Software Engineer at Microsoft, previously at Myntra.

I help engineers crack System Design interviews through personalized 1:1 mock interview sessions designed to mirror real hiring loops.

What you’ll get in a 1:1 HLD Mock Interview

🎯 Realistic system design simulation tailored to your target role & company

💬 Actionable, real-time feedback on your architecture and communication

🏗️ Learn to design scalable, reliable, and production-ready systems

⚖️ Build clarity around trade-offs, bottlenecks, scalability, and reliability

🗣️ Improve your storytelling, structure, and ability to communicate complex systems

What we’ll practice

You’ll learn how to:

• Clarify requirements and identify functional & non-functional requirements
• Estimate traffic, storage, bandwidth, and capacity
• Break a system into high-level services and components
• Design APIs, data models, and service boundaries
• Handle millions of users and high-volume traffic
• Apply caching, sharding, replication, queues, and load balancing
• Design for availability, reliability, fault tolerance, and disaster recovery
• Identify single points of failure and system bottlenecks
• Evaluate architecture trade-offs and explain why you chose a particular approach
• Handle deep-dive follow-ups and changing requirements

Whether you're designing a URL shortener, notification system, chat application, payment system, news feed, or large-scale cloud service, the focus is on developing the structured thinking interviewers look for.

The goal isn't just to draw an architecture diagram.

It's to learn how to reason about large-scale systems, communicate your decisions, and defend your design under pressure.

Walk into your next System Design interview structured, confident, and interview-ready — backed by real industry experience.
