Building an AI-Powered Interview Preparation Platform: A Developer's Journey🔥

Hey DEV Community! 👋 I'm excited to share a project I've been working on: an AI-powered interview preparation platform. This tool helps users practice for job interviews using AI-generated feedback. Here's an overview of the project and some technical insights.

PrepMasterAI

Project Overview

The platform allows users to:

  • Answer mock interview questions via voice or text input
  • Receive AI-generated feedback on their responses
  • Get a detailed analysis of their strengths and areas for improvement

Tech Stack

  1. Frontend: Nextjs with Javascript

  2. AI Model: Google Gemini AI model for interview analysis

  3. Speech-to-Text: react-hook-speech-to-text NPM package used for voice to text

Key Challenges and Solutions

Accurate Speech Recognition

  1. Implemented noise cancellation and used the Web Speech API for better accuracy Added a text editor for users to correct any transcription errors

Real-time AI Analysis

  1. Used web workers to run the AI model in the background, ensuring a responsive UI Implemented a queue system to handle multiple requests efficiently

Personalized Question Selection

  1. Developed an algorithm to dynamically select questions based on user performance and job role

Data Privacy

  1. Implemented end-to-end encryption for voice data Used tokenization to anonymize user data for AI training

I'd love to hear your thoughts, suggestions, or questions about the project. Have you worked on similar AI-powered tools? What challenges did you face?
