AI Voice Interview: The Impact of AI Interviewer Technology on Hiring Efficiency

Table of Contents

The world seems to move at a slower pace when you’re on hold.

It’s as if time itself decides to take a nap while you listen to the same elevator music loop that replays 1,000 times. A small, but irritating moment we all know and love (not). It’s incredible how a few minutes of waiting can make you feel disconnected from everything else; how something so minor can make us even more aware of how fast everything else is moving. In other parts of our life, we’ve been accustomed to things just happening quickly. We send over a text and get a reply almost immediately. We order food online, and it’s at our door in minutes. We click this and that, then expect it to be done fast, easy and efficient.

Yet, in hiring, we’re often in many drawn out processes, leaving us waiting far longer than we’d like. A lot of times, and due to countless factors, it’s not always feasible to have any sort of delay.

To reduce the delays in candidate screening, agencies have been replacing those indefinite pauses with a more fluid hiring experience, where AI voice interviews move things forward with intention bringing your hiring decisions closer to completion. As expectations spring up and time becomes an even more precious commodity, companies are reimagining processes to be in line with the pace of modern recruitment. Let’s take a look below at how candidate screening software like AI voice interviews are making recruitment more efficient and actionable.

What Is An AI Voice Interview?

An AI voice interview is a virtual conversation between a candidate and an automated system, powered by artificial intelligence. The questions and structure for these AI interviews are generally set during the agent preparation where you specify your needs, and some AI interview tools even have features to automatically generate suggestions that guide you. This kind of automation in talent acquisition shrinks time to hire considerably, and eliminates the reliance on manual interview scheduling through platforms like Zoom, Teams, Calendly etc. Additionally, the biggest benefit is the ability for recruiters to standardize their candidate assessment efforts at a highly amplified rate.

That’s the ‘what,’ but what about the ‘why’?

Let’s turn our attention to the larger trends in recruitment that are making this technology so impactful.

Why AI Voice Interviews Are Becoming Common in Recruitment

If you’ve been following our blog, you’ve probably heard us mention the impact of AI voice interviews in staffing and recruiting a million times by now. Thanks for sticking around! For those new to the conversation, we’re glad you’re here. Rather than just explaining why they’ve become so common, we thought we would show you, through a simple scenario comparison on how this change is unfolding for many.

So, let’s imagine the traditional hiring process for a minute. Without AI, it looks a lot like this:

Monday: Post the job

Tuesday: Review resumes

Wednesday: Review resumes and outreach

Thursday: Schedule initial calls

Friday: Schedule initial calls

Next week: Start first interviews

Zoomed out, it looks like a lot of back-and-forth, and a lot of waiting. This is how things can flow with AI voice interviews on board, where your screening starts the day you share an open role:

Monday: Post job and candidates begin AI interviews

Tuesday: Review responses, identify top candidates

Wednesday: Follow up and final assessments as needed

Thursday: Submit viable candidates to clients for review

Friday: Review more applicants, and schedule interviews with top picks

Efficiency from AI talent assessment in the process gives us the space to better understand the people behind the roles, making it more about them than the task at hand. Remember how hiring used to be, constantly rushing through resumes, hastily scheduling calls, and trying to make quick decisions to please others. It was all about urgency. With AI voice interviews, that frantic pace is no longer necessary, and you are met with higher quality hires a lot sooner.

Getting the Best Results from AI Voice Interviews

Getting the best results from these virtual interview platforms starts with understanding how the AI learns from us.

Building Your Interview Agent

You're essentially teaching it what’s important for your roles. This is super powerful, but it’s also something we need to be careful with. As journalist Hilke Schellman puts it, “One biased human hiring manager can harm a lot of people in a year, and that's not great.” We have control when we co-create an experience with AI. We actively guide it by choosing what it collects and assesses, so be mindful. Before going live, they give us a chance to:

  • Review questions before they are asked
  • See patterns in how different candidates are evaluated
  • Make adjustments when we notice any unfair trends
  • Create standard questions that are objective and treat everyone equally

To Get Optimal Results

  • Use clear and inviting language everyone can understand
  • Prioritize the skills that align with the job, not only background
  • Give all candidates the same opportunities to share their experience
  • Review and update your interview questions regularly
  • Review candidate experiences and be open to accommodate certain needs

Technical Setup

Implementing these systems can seem like a lot at first. 46% of hiring teams admit to facing technical difficulties in integrating AI, and these tips should help make it a lot more manageable:

  • Provide clear, step-by-step setup instructions
  • Test the system internally, then with a small group
  • Have a support person available for help, and a designated team or individual to oversee things
  • Offer training to make sure everyone feels confident using them
