Mock system design interview (HLD)

System design interviews aren't just about drawing boxes; they are about justifying trade-offs under extreme pressure. I have designed systems that handle the massive scale of YouTube and YouTube Studio, where 'scalability' isn't a buzzword—it's a requirement for billions of users.

Having cleared system design loops at Apple, Microsoft, and Uber, I know exactly how top-tier companies evaluate candidates. In our sessions, we will move beyond basic architecture and dive into the deep end: data partitioning, consistency models, and handling failure at scale. Book a session to transform your vague ideas into a concrete, engineering-led design.

Format: Standard 60-Minute Interview Loop To provide the most realistic practice, we will stick strictly to the timeline used in actual big-tech interviews:

• The Intro (0-5 mins): A quick introduction to break the ice and set the stage, exactly like a real loop.
• The Deep Dive (55 mins): We go straight to the design. I will present a vague problem statement (e.g., "Design a notification system"), and you will drive the architecture, trade-offs, and scalability decisions while I probe your reasoning.
• Feedback & Strategy (Last 15 mins): We stop the clock for a detailed debrief. I will break down your performance on requirements gathering, high-level design, and deep-dive components, giving you actionable steps to improve before your real interview.
