Voice AI for Mock Interviews
By Serena Wang on April 7, 2025

About ParrotPrep
ParrotPrep is an AI-powered mock interview platform designed to help job seekers prepare for interviews through realistic practice sessions. Offering customizable AI interviews across Software Engineering, Data Science, Sales, and Business Consulting, their mission is to eliminate interview anxiety through thorough preparation, guided by the principle: "If you fail to prepare, you are preparing to fail."
The platform features Polly, an AI interview assistant powered by Hume's Empathic Voice Interface (EVI), allowing users to practice interviews through voice interactions and receive tailored feedback on both technical and emotional performance.
The Challenge
ParrotPrep faced several challenges in building a platform that could truly prepare job seekers for real-world interviews:
Natural Interview Experiences: They needed to simulate realistic interview scenarios that felt natural and responsive, rather than scripted Q&A sessions.
Comprehensive Feedback: Beyond practicing questions, ParrotPrep wanted to offer actionable insights on both verbal content and emotional delivery. These insights had to adapt to different industries as well.
The Solution: Empathic Interview Coaching with EVI
Since integrating Hume's EVI, ParrotPrep has seen significant improvements:
- 5.6x increase in session duration: Users now spend an average of 14.5 minutes per session, up from 2.6 minutes with text-only prototype
- 41% increase in user retention: More users returning within 7 days compared to pre-EVI implementation
- 83% user preference: Users consistently rate ParrotPrep's simulations as more realistic than competitors
- 40% improvement in confidence scores for users receiving emotional feedback over multiple sessions
User Success Story: Edwin, a first-generation college student, used ParrotPrep's emotional analysis to identify communication patterns like frequent qualifiers ("I think," "maybe") that undermined his credibility. Through consistent practice, his confidence scores steadily improved, and he ultimately secured a consulting role, crediting ParrotPrep with providing high-quality coaching previously only accessible to those who could afford expensive human coaches.
ParrotPrep's partnership with Hume demonstrates how empathic AI is revolutionizing interview preparation, helping job seekers worldwide build confidence and achieve their career goals through realistic, emotionally intelligent practice.
