Screening tools aren’t just about speed anymore, they’re about clarity, depth, helping recruiters make real decisions faster and close more hires.
Platforms like HeyMilo and Spark Hire are solving different problems in that journey. While both offer ways to streamline interviews through software, the experience, outputs, and level of flexibility they provide vary widely.
Spark Hire is best known for structured one-way video interviews—used mostly in early-stage screening. HeyMilo, on the other hand, is designed for interactive AI led voice and video interviews that adapt in real time and deliver results that go deeper than a recording ever could.
If you're evaluating these tools, below is a breakdown of how each platform performs when it comes to candidate experience, recruiter workflows, and actual results—so you can choose the one that matches how your team works.
Different Designs, Different Outcomes
HeyMilo AI is built for teams that need real interviews at scale—without sacrificing depth. Candidates engage in structured phone or video interviews with an AI recruiter that adapts in real time based on how they respond. The platform captures clarity, confidence, and decision-making, then delivers structured results your team can use to move quickly. It's designed for high-volume hiring where every signal counts, and recruiters need more than just a recording that they need to manually review for insights later.
Spark Hire is centered around asynchronous one-way video. Candidates record responses to preset questions, and recruiters review them later. It works well when you need consistency across high volumes and want to hear directly from candidates in the early stages. Spark Hire also offers a broader suite, including automated reference checks and behavioral assessments.
Both tools streamline screening—but they’re built for different kinds of teams, workflows, and outcomes.
Candidate Experience
HeyMilo gives every candidate a shot to actually show who they are, not just hit record and hope for the best. Interviews happen over phone, web audio or video, with AI guiding the conversation and asking follow-up questions when things are vague or could go deeper. It's conversational, not canned—and available anytime. That means fewer hoops for candidates, and better signal for your team right from the start.
Spark Hire is built around one-way video. Candidates record answers to set questions on their own time, and hiring teams review when it fits their schedule. It’s structured and predictable, which works well for teams that want consistency—but doesn’t leave room for follow-up or unscripted insight.
If you’re screening at scale, both reduce friction. But the feel and the quality of what you learn depends on what kind of experience you want to deliver for both sides.
Recruiter Workflows
HeyMilo is built for speed, structure, and scale. Interviews are fully customizable by role, client, or region—so your team sees the signal that matters, not generic feedback. Each response is scored in real time using a role-specific rubric, with transcripts, summaries, and recordings delivered straight into your ATS. Whether you're managing 50 open reqs or 500, HeyMilo lets you move quickly without compromising on depth or consistency.
Spark Hire offers flexibility for teams that want to stay hands-on. Recruiters build question sets, send invites, and manually review candidate recordings. It works well when you’ve got a smaller volume of roles—or when collaboration between hiring managers and recruiters is a bigger priority than speed.
At the end of the day, it comes down to how your team operates: Do you want to spend time reviewing footage, or reviewing rich insights and making faster calls?
Use Cases and Flexibility
HeyMilo supports high-volume hiring across industries—staffing firms, BPOs, franchises, and corporate recruiters use it to pre-screen for roles in healthcare, education, field services, customer support, and more. The platform’s flexibility makes it easy to spin up new interviews, tailor them to specific clients, and scale screening without adding more recruiter hours (while staying within your budget).
Spark Hire is often used by leaner in-house teams hiring for early-career or hourly roles. Its async video format works well for structured, repeatable screenings in industries like retail, manufacturing, and logistics—especially when teams want hiring managers to be closely involved in reviewing candidate videos.
One important distinction: Spark Hire’s broader product suite includes candidate-facing tools, assessments, and an ATS—which can blur the line between partner and competitor for staffing firms. If you’re hiring on behalf of clients, it’s worth understanding how candidate data is handled across their ecosystem.

Final Thoughts
HeyMilo and Spark Hire both help streamline early-stage screening—but they’re built for different hiring goals.
Screening interview tools like HeyMilo are designed for staffing firms and high-volume recruiters who need flexible, structured interviews that scale. It adapts in real time, integrates with your existing workflows, and delivers rich insights that help recruiters move fast with confidence. Importantly, HeyMilo is not part of a candidate marketplace—so your data stays yours.
Spark Hire, on the other hand, is great for teams that want a video-based experience with simple collaboration features. It works especially well for lean in-house teams focused on repeatable roles, and its built-in ATS can be useful if you're consolidating tools.
When choosing between them, consider your volume, your team’s workflow, and whether you want deep insights or simpler video playback. Both tools offer structure—but the outcomes, ownership, ROI and scalability look very different.
