The NEW Fireflies AI Voice Agent is INSANE - Set One Up in 5 Minutes
Tired of wasting hours on screening calls and sales qualification? Fireflies' revolutionary AI voice agent can conduct interviews, qualify leads, and handle support calls for you - with human-like conversation skills. We'll show you exactly how to configure your own automated interviewer or sales agent in minutes, complete with custom questions and brand personality.
What Fireflies Voice Agent Can Do
Most businesses know they should be more consistent with candidate screenings and lead qualification - but finding time for these repetitive calls is nearly impossible. Fireflies, previously known for its meeting transcription AI, has now launched voice agents that can actually participate in calls on your behalf.
Unlike basic IVR systems, these agents conduct natural, dynamic conversations. They can ask follow-up questions based on responses, reference uploaded documents, and adjust their tone based on your instructions. The technology represents a massive leap from scripted bots to true conversational AI.
Key capability: The agent doesn't just transcribe - it actively participates in Zoom/Google Meet calls as a full participant, handling the entire conversation flow from greeting to conclusion.
Practical Use Cases
Business owners and HR managers are drowning in time-consuming but necessary calls. The Fireflies voice agent solves this by automating four critical conversation types:
1. Screening Interview Agent
Conducts first-round candidate interviews with preset questions about experience, skills, and cultural fit. Automatically filters unqualified applicants before they reach human recruiters.
2. Sales Discovery Agent
Qualifies inbound leads by asking discovery questions about business needs, budget, and timeline. Captures key information for your sales team to prioritize follow-ups.
3. Progress Checking Agent
Conducts regular check-ins with team members to track project status, identify blockers, and gather updates - without scheduling meetings.
4. Customer Support Agent
Handles tier-1 support inquiries by answering common questions from knowledge bases and escalating complex issues to human agents.
Real-world impact: Early adopters report saving 15+ hours per week on screening calls alone, while improving response times and candidate experience.
Step-by-Step Setup
Creating your first voice agent takes just minutes. Here's exactly how to configure an interview screening agent:
Step 1: Create Custom Agent
Select "Custom Agent" in Fireflies and choose "Screening Interview" as the template. Give your agent a name like "Technical Recruiter Assistant" and select the relevant role (e.g., AI Engineer).
Step 2: Configure Questions
Add your screening questions in order. For technical roles, include:
- "Walk me through your current role and responsibilities"
- "What tools do you use most in your work?"
- "Describe a recent project and your contribution"
- "What challenges do you typically face?"
Step 3: Add Knowledge Base
Upload your company website, job description PDF, and any technical documentation. This helps the agent answer candidate questions about your company and role specifics.
Step 4: Set Instructions
Define the agent's personality and conversation flow. Example:
"Greet candidates warmly, ask how they're doing. Be professional but friendly. Ask questions directly, allowing time for responses. For unclear answers, ask one follow-up for clarification. Thank candidates for their time at conclusion."
Step 5: Choose Voice & Duration
Select from multiple voice options (male/female, various accents) and set session length (10-40 minutes). Preview the voice to ensure it matches your brand tone.
Step 6: Share Interview Link
Copy the unique URL to send to candidates. They'll enter their name/email and join a call with your AI interviewer.
Prompt Engineering Tips
The quality of your voice agent depends heavily on your prompt engineering. These professional techniques create more effective conversations:
1. Define Clear Objectives
Start your prompt by stating the interview's purpose: "The primary goal is to assess technical skills in LLM engineering while evaluating cultural fit." This focuses the agent's analysis.
2. Structure the Flow
Break the conversation into sections: warm introduction, technical assessment, situational questions, and closing. Specify time allocations for each.
3. List Key Competencies
Identify exactly what to evaluate: "Assess for: 1) Hands-on experience with Voiceflow 2) Python API integration skills 3) Client requirement balancing."
4. Provide Evaluation Criteria
Tell the agent what good answers sound like: "Strong candidates will mention specific projects, challenges overcome, and measurable outcomes."
Pro tip: Include example dialogues showing ideal question-answer sequences. The more examples you provide, the better the agent mimics your preferred style.
Cost Structure
Fireflies uses a credit system for voice agent calls:
- 1 credit = 1 minute of conversation
- $5/month: 50 credits (5-7 screening calls)
- $18/month: 200 credits (20-30 calls)
- $600/month: 10,000 credits (high-volume sales teams)
For most businesses, the $18 plan covers weekly screenings and regular sales qualifications. The system automatically pauses agents when credits run low, preventing unexpected overages.
Cost comparison: At $18 for 200 minutes, you're paying $0.09/minute - compared to $25-50/hour for human recruiters or SDRs to conduct the same calls.

In summary: Fireflies' voice agent can save your team 10+ hours weekly on screening calls and lead qualification while improving response times. For under $20/month, you get an always-available interviewer or sales qualifier that works in your voice, follows your script, and integrates with your CRM.
