Build an AI Mock Interview Application with React and Next.js

This article guides you through the process of building an AI-powered mock interview application using React and Next.js. This application leverages AI to conduct interviews based on a candidate’s resume and skills. An accompanying video walks through the full process. The application features user authentication, a dashboard to manage mock interviews, and AI-driven question generation with detailed feedback.

Learn how to create a full-stack AI mock interview application using React and Next.js. This app features secure authentication, a user-friendly dashboard, and AI-powered interview simulations. Customize interview parameters such as job role, experience level, and desired technologies. The AI dynamically generates questions and provides detailed feedback on user responses, enhancing interview preparation.

Application Overview

The application boasts a clean and intuitive landing page with a secure authentication service, ensuring user data protection. Once logged in, users access a dashboard where they can create and manage mock interviews. Each interview can be customized based on specific job roles, required skills, and experience levels. The system uses this information to generate relevant interview questions. Users can specify the job role they want to practice for, such as “Fullstack Developer,” and provide a job description or a list of technologies they expect to be questioned on, such as React, Java, Spring Boot, Node.js, and MySQL. They can also indicate their years of experience, which helps the AI tailor the difficulty of the questions.

The Interview Process

Initiating a mock interview is straightforward. The AI model generates questions based on the information provided by the user. The interview interface is designed to simulate a real-world interview scenario. The interview page displays the details entered by the user, along with options to enable the webcam and microphone, creating a more immersive experience. Once the interview begins, the AI presents a series of questions. Users can record their answers, and the application saves these responses using PostgreSQL and an ORM. After each question, users can review their recorded answers and proceed to the next question. Once the interview is complete, the AI provides feedback on each answer, including a rating, a sample correct answer, and specific feedback on the user’s response.

Reviewing Feedback and Retaking Interviews

The application stores all completed interviews, allowing users to review their performance and track their progress. From the dashboard, users can access previous interviews and view detailed feedback on their answers. A key feature is the ability to retake interviews. This allows users to practice and improve their responses based on the feedback received. The system retains all previous feedback, enabling users to compare their performance over time and identify areas where they have improved.

Technologies Used

This application is built using a modern technology stack, including:

React: A JavaScript library for building user interfaces.
Next.js: A React framework for building server-rendered applications, offering features like file-based routing.
PostgreSQL: A robust open-source relational database for storing user data and interview responses.
AI Model: A custom-trained AI model to generate relevant interview questions and provide feedback on user answers.

Next.js is particularly useful because of its folder-based routing, which simplifies the development process. Even if you’re new to Next.js, the development process is designed to be beginner-friendly, with step-by-step guidance throughout.
