Interview Assistant -- AI Powered Interview Preparation and Assessment Platform
Bibliographic record
Abstract
ABSTRACT: In today’s highly competitive job market, effective interview preparation plays a pivotal role in achieving career success. However, conventional preparation methods often fail to provide personalization, real-time feedback, and comprehensive performance assessment. To address these challenges, this research presents the AI-Driven Interview Assistant — an intelligent, adaptive, and comprehensive AI-powered interview preparation and assessment platform. The proposed system leverages Natural Language Processing (NLP), speech analysis, and computer vision to simulate realistic interview environments while delivering actionable feedback and personalized improvement recommendations. The platform employs Large Language Models (LLMs) such as OpenAI’s GPT and Google’s Gemini for intelligent question generation and response evaluation. Real-time speech-to-text conversion using Google Speech-to-Text API or Whisper AI enables seamless voice interaction, while sentiment analysis with Hugging Face transformers evaluates emotional tone, confidence, and engagement. The core evaluation engine analyzes responses based on content relevance, communication clarity, technical accuracy, and behavioral competence. Optional computer vision modules assess facial expressions and body language for holistic performance insights. From a technical standpoint, the system is built with a React.js frontend and Node.js/Express backend, ensuring a smooth, interactive user experience. WebRTC integration enables live audio-video interview simulations, while MongoDB or PostgreSQL store detailed performance analytics for adaptive learning. The platform also integrates with job portals and company databases to deliver role-specific and industry-oriented interview preparation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
