Practice job interviews with voice-based Google Gemini AI interviewer

What does this workflow do?

This workflow acts as the backend "brain" for a sophisticated AI Voice Interviewer. It receives a user's resume text and a target job description, then uses a Large Language Model (LLM) to conduct a realistic, voice-based interview. The workflow maintains conversation history to ask relevant follow-up questions, creating a dynamic and personalized interview practice experience.

This template is designed to work with a simple HTML frontend that handles the voice-to-text and text-to-speech functionality.

What services does this workflow use?

• Google Gemini: This is the LLM used to generate intelligent interview questions. You can easily swap this out for other models like OpenAI.

What credentials do you need to have?

You will need one credential:

• A Google Gemini API Key. You can get one for free from the Google AI Studio.
