I am producing a short demo video for an AI-powered career platform. The product is an AI interview simulator - a real-time voice interview where an AI interviewer asks adaptive questions and then scores the candidate. I need one person to BE the candidate in that interview, and to record it themselves at home. This is not a voiceover reading job. There is no script. You log into an account I provide and take a real AI voice interview. The AI asks unpredictable follow-up questions, so you need to think and speak naturally for about 8-10 minutes per run. You will answer as YOURSELF, using your own real work experience - so there is nothing to memorise and nothing to invent. What you send me beforehand is an ANONYMISED version of your own CV: - Replace y...
