Practice Job Interviews with Voice-based Google Gemini AI Interviewer

This n8n workflow serves as the intelligent backend for a voice-based AI job interviewer. It processes user-submitted resume text and target job descriptions via a webhook, leveraging Google Gemini to generate realistic interview questions. The system maintains conversation history, enabling follow-up questions that adapt to user responses, simulating a genuine interview experience. Designed to pair with a simple HTML frontend for voice-to-text and text-to-speech handling.

Key features include seamless integration with Google Gemini API for natural language processing, making it easy to swap for other LLMs like OpenAI. Setup requires only a free Gemini API key and activation of the workflow. The frontend, available on GitHub, connects via the webhook's production URL, allowing users to practice interviews hands-free.

Benefits include personalized interview preparation, skill assessment through adaptive questioning, and unlimited practice sessions without human interviewers. Ideal use cases: job seekers honing responses for tech, sales, or executive roles; career coaches providing scalable training tools; HR teams simulating interviews for internal development. Saves time and boosts confidence with realistic, voice-driven interactions.

To deploy: Clone the GitHub frontend, configure Gemini credentials in n8n, copy the webhook URL, and start practicing. Perfect for Development & IT professionals automating testing and training workflows.
