An honest, side-by-side breakdown of Astrnt and Spark Hire — plus why forward-thinking recruiting teams are choosing InterviewFlowAI instead.
Both tools serve the recruiting and hiring space — but they take very different approaches. Here's what each platform actually does.
Simple async video interviews for high-volume hiring
Astrnt (formerly astrnt.co) is an asynchronous video interviewing platform designed for high-volume hiring, particularly popular in Southeast Asia and APAC markets. Candidates record video answers to pre-set questions at their own pace, enabling faster screening at scale.

Spark Hire is one of the world's largest video interviewing platforms, used by 7,000+ organizations. It offers one-way asynchronous and live video interviews, AI-assisted transcription and scoring, and — following its 2023 acquisitions of Comeet (ATS) and Chally (behavioral assessment) — now provides a comprehensive hire-to-offer recruiting suite.
