High Level Design Interview

Understand how large-scale systems are designed, what trade-offs to make, and how to think from a scalability perspective.

We’ll deep dive into one real system design question and discuss how top engineers approach architecture, scaling, and reliability.

What we’ll do:

• Pick a system like Instagram, WhatsApp, or URL Shortener
• Define requirements and constraints clearly
• Design key components (API, DB schema, cache, load balancing, etc.)
• Discuss trade-offs, data flow, fault tolerance, and scaling strategies
• Review your communication & diagram presentation skills

Outcome:

By the end, you’ll have a practical framework for tackling HLD questions with confidence and explaining your design like a pro.
