## What it is
A curated collection of low-level design (LLD) and machine coding interview questions with Java implementations, gathered from major tech company interviews. It helps candidates practice object-oriented design problems commonly asked in SDE interview rounds.

## Use cases
- prepare for low level design interview rounds
- practice machine coding questions asked at tech companies
- study object-oriented design problems with Java solutions
- find real LLD interview questions from companies like Flipkart and Udaan
- review design patterns used in working code solutions

## When to choose
- you are preparing for SDE-I or SDE-II interviews with machine coding rounds
- you want real interview questions with reference implementations in Java
- you need practice with object-oriented design and data modeling problems

## When to avoid
- you need high-level system design (HLD) resources instead of LLD
- you want a production-ready library or framework rather than study material
- you prefer solutions in languages other than Java

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: education, tutorials, programming-languages
- platform: jvm, cross-platform
- tags: interview-preparation, low-level-design, machine-coding, object-oriented-design, java, system-design
