If you're screening more than a handful of candidates a week, one-way video interview software has probably come up on your radar.
It solves a real problem: getting past the resume without spending hours on the phone. Candidates record their answers. You watch when it suits you. You screen 30 people without booking a single meeting.
It works. It's better than phone screens. But there's a catch -- and most recruiters only notice it after they've been using the tool for a while.
What Is One-Way Video Interview Software?
One-way video interview software lets you send candidates a set of pre-written questions, then record themselves answering on their own time. You review the recordings later and decide who to advance.
The "one-way" part is literal: the candidate talks, you watch. There's no back-and-forth. No real conversation. No follow-up questions.
Popular tools in this category include:
- Willo -- Australian and UK-focused, SMB-friendly pricing
- Spark Hire -- strong US market presence, good ATS integrations
- HireVue -- enterprise-grade, significant price tag
- VidCruiter -- customisable but complex
All of them work roughly the same way: you build a question set, send a link, review recordings.
The Problem With Traditional One-Way Video
Here's where most tools fall short.
When a candidate records themselves answering fixed questions, you get a polished presentation. You don't get a conversation. And conversations are where you actually learn who someone is.
Think about your best interviews. What made them good? It wasn't that the candidate answered your five questions well. It's that when you asked "tell me about a time you led a project," they gave an interesting answer -- and you followed up. You dug in. You got to the real story.
Traditional one-way video software can't do that. The question set is fixed. Every candidate gets the same script. There's no follow-up. The tool is passive -- it captures what happens, but it doesn't drive the interview.
The result: you end up reviewing recordings of candidates delivering rehearsed answers, then trying to guess whether they're actually good.
A Different Approach: AI-Conducted Interviews
Yelm takes a different approach. Instead of recording candidates answering your static questions, Yelm's AI interviewer conducts a live, dynamic conversation.
Here's how it works:
- You set the role and the areas you want to explore
- Candidates get a link and complete the interview on their schedule
- Yelm's AI avatar conducts the interview -- asking questions, listening to answers, and following up based on what the candidate actually says
- You get a ranked shortlist, AI-generated scores, and a transcript for every candidate
The AI doesn't just ask your five questions in order. It responds to the candidate's answers. If they mention an interesting project, it asks about it. If their answer is vague, it probes. It's the closest thing to a real structured interview -- conducted at scale, without your time.

Is One-Way Video Right for Your Hiring Process?
One-way video software -- any flavour -- works best when:
- You have high application volume and need to thin the field efficiently
- You're hiring for repeatable roles (same questions, same bar across the board)
- You need to involve multiple stakeholders without syncing calendars
- You want candidates to complete the process on their schedule, not yours
If you're hiring one or two senior roles a year, one-way video is probably overkill. If you're running ongoing hiring across a growing team -- it's a material time save.
What to Look for in Video Interview Software
Before you pick a tool, get clear on these:
1. Does it actually save you time? Watching 30 five-minute recordings is still 150 minutes. If the tool doesn't surface insights quickly -- AI summaries, scores, flagged moments -- you've moved the work, not eliminated it.
2. What's the candidate experience like? Candidates form opinions about your company from your hiring process. A clunky, impersonal tool sends a signal. A smooth, professional experience (even if it's AI-led) keeps good candidates engaged.
3. How does it integrate with your existing stack? If you use an ATS, check what integrations are available before signing up.
4. What does it cost at your volume? Most tools charge per seat or per interview. Run the numbers for your actual hiring volume, not the lowest tier on their pricing page.
