Retell AI - API That Turns Your LLM Into A Human-Like Voice Agent

Retell AI Basics: Everything You Need to Start Building Voice Agents

Vision

Twenty years ago, every business found itself needing a website, the new gateway to the world. Platforms like WordPress and Squarespace rose to become the standard for getting businesses online.

Today, a new revolution is here. Every business that relies on phone interactions can now have an AI voice agent of their dreams. A tireless and empathetic receptionist, salesperson, debt collector, or appointment reminder that works 24/7. Operational bottlenecks vanish overnight. Doubling your business no longer means doubling your team. Customer experience no longer suffers. (Ever tried calling an East Coast bank after 3 p.m. PT?) But companies aren't ready. Platforms don't exist.

At Retell, we're pioneering the new standard for building AI voice agents. With seamless UI, comprehensive toolkit, effortless integrations, thriving builder community, we're creating everything businesses need to deliver exceptional phone interactions on every single call.

Join us—because the future of AI voice agents is coming anyway, so why not be the one who defines it?

Interview Process

Introduction

We'll begin by introducing ourselves and learning about each other’s background. We'll also take time to answer any questions about the role. The session will conclude with a mini mock project: three questions to research and prepare.

Phone Interview 1

A 30-minute interview focused on communication, conflict resolution, and judgment. This will be conducted using a collaborative document and will involve working through a hypothetical scenario.

Phone Interview 2

A 30–45 minute interview centered on tool use. You may be asked to use a SaaS tool to demonstrate how you would implement automations or drive efficiency within a company.

Onsite

This step involves 1–4 hours of interviews, conducted onsite in the San Francisco Bay Area. For candidates located outside the Bay Area, the interviews may be conducted virtually.

Please bring a computer for hands-on tasks during the interviews.

There are up to two interview rounds:

• A practical session assessing organizational skills, process thinking, prioritization, and the ability to set up efficient workflows.
• A research session focused on exploring a product to demonstrate your communication style, thought process, and product sense.
