Interview Optimiser is an AI-powered platform that helps job seekers prepare for interviews through realistic voice-to-voice mock interviews. Their mission is to equip candidates with confidence and clarity by simulating high-pressure interview scenarios, delivering dynamic, adaptive conversations and providing actionable insights on vocal delivery such as tone, confidence, and emotional regulation. The platform's integration of Hume's Empathic Voice Interface (EVI) technology enables it to conduct voice-to-voice mock interviews that adapt to candidates' responses, simulating real-world interview pressure. This has resulted in a 76% cost reduction per session while enhancing user engagement and retention. With the EVI API, Interview Optimiser offers three key capabilities: Real-Time Voice-to-Voice Interviews, Prosody-Based Feedback, and Cost Efficiency. The platform's tools powered by Hume include an Adaptive Interviewer, Confidence & Clarity Scoring, and Recruiter Analytics (B2B), which empower candidates and recruiters to improve interview performance and streamline hiring processes.
