Engineering Interview Prep Website

# Project Title

**Build a Premium Interview Preparation Platform for Data Engineers**

## Project Overview

I want to build a modern, premium-looking web application specifically designed for **Data Engineers** to prepare for technical interviews.

The main objective is to create a single platform where users can quickly revise interview concepts before an interview instead of searching through multiple websites, PDFs, or YouTube videos.

The platform should be visually appealing, fast, responsive, and provide an excellent user experience on both desktop and mobile devices.

This will be a **paid membership platform**, where users create an account, purchase a subscription, and access premium interview preparation content.

# Future Vision

This is not a one-time project.
