Where async wins
- High-volume top-of-funnel. When you have 800 applicants for a junior role, async screens at 5x throughput vs phone screens.
- Time-zone-spread candidate pools. No coordination overhead.
- Standardized initial screen. Same 3 questions, same evaluation.
Where async fails
- Senior / executive roles. Real conversation matters. Async signals "we're not invested."
- Cultural fit assessment. You can't gauge how someone navigates ambiguity from a 90-second video.
- Cold-source / passive candidates. They didn't sign up for this; they signed up for a conversation.
The right format
- Max 3 questions, 90 seconds each.
- Allow one re-record per question.
- Submit deadline of 48 hours, not 7 days.
- Fast turnaround on review (within 3 business days).
What candidates hate
- "Submit a 5-minute video answering 8 questions about why you're a fit."
- Proprietary recording platforms that need a webcam test.
- AI-only review (no human on the other side).
Bottom line
Async interviews are a tool, not a strategy. Use them in the right context, communicate clearly that a human will review, and turn them around fast.
