In this video, we run a full system design mock interview focused on designing LeetCode from scratch, exactly the way it is expected in FAANG-level interviews ft. Vanshika Agarwal - Google engineer.
You will see how to approach an open-ended system design problem step by step, starting from requirement clarification to high-level architecture and deep dives. The discussion mirrors real interview expectations for mid to senior software engineering roles.
This mock interview is especially useful if you are preparing for system design rounds at Google, Meta, Amazon, Apple, Netflix, or similar product-based companies.
