I created a FREE Low Level Design (LLD) Interview Resource

Ashish Pratap Singh

Mar 09, 2025

I’m excited to share that you can now prepare for Low-Level Design (LLD) Interviews for FREE at algomaster.io.

Check it out here

It includes structured resources to help you study:

Object-Oriented Programming (OOP)
Design Principles
Design Patterns
UML Concepts
LLD Interview Problems, categorized by difficulty

You can also:

Filter & search through topics
Track your progress by marking topics as complete
Experience resources based on your preferred programming language—supports Java, Python, C++, C#, and Go

Previously, I shared LLD learning resources in a GitHub repository with 12,000+ stars, which many found valuable. However, it had limitations—no filtering, no language-based experience, and no progress tracking.

I've added it to AlgoMaster.io to solve these issues and provide a better learning experience.

I plan to keep improving the platform—adding UML diagrams, real-world use cases, and much more to make it the best resource for mastering LLD interviews.

Check it out here

Thank You,

Ashish

This a great resource, Ashish! One thing I do notice is, most of the LLD questions have been implemented without design patterns. Apart from singleton, none of the other common design patterns like observer, factory or strategy has been used. The usage of single patterns is an important benchmark for LLD interviews. What are your thoughts on this? Thanks.
