Uber & Rubrik System Design Coding Rounds | Multithreading Interview Questions | Placement Series 3

Submit your questions here: https://forms.gle/2QhNBhdjb7UwjteE8

In this livestream, I’ve solved and broken down two real-world system design coding questions asked in top company interviews:

Rubrik - Designing an optimal queuing system
Uber - Implementing Java’s Scheduled Executor Service

I discuss the concepts like minimizing waiting time, avoiding starvation, Shortest Job First algorithm, multithreading, thrashing, and more.

If you want to prepare for MAANG interviews or level up for college placements, this stream will give you deep insight into how high-quality solutions are structured and how to think like a senior engineer.

This is Part 3 of the Placement Series, where we solve real-world questions from online assessments, interviews, LLD, and HLD rounds conducted by top companies. Perfect for internship and placement preparation.
