You're researching HeyMilo vs Classet because manual phone screening is killing your team and spring hiring season means you need volume now. Both tools promise to handle first-round interviews automatically, but they take completely different approaches to reaching candidates. One requires candidates to check messages, find time, and click through to video or web interviews. The other calls them within seconds of applying, before they've moved on to the next opportunity. For skilled trades where ghosting is common and qualified candidates are scarce, whether you reach people while they're still interested makes all the difference.
TLDR:
- Classet engages candidates within seconds of applying via phone, while HeyMilo sends invitations for candidates to complete at their own pace
- Joy's phone-only format increased completion rates from 50% to 70%+ for Sears Home Services because frontline workers could talk instead of type
- Classet integrates with 100+ ATS systems in days without engineering work, ideal for high-volume hiring organizations
- HeyMilo's SOC 2 certification was completed through Delve, a platform facing fraud allegations in March 2026, while Classet holds SOC 2 Type II from Prescient Assurance and uses OneLeet for continuous security management
- HeyMilo offers video interviews and detailed scoring for staffing agencies presenting candidates to clients
- Classet specializes in AI phone screening for high-volume hiring in retail, hospitality, healthcare, and skilled trades where speed determines whether you reach candidates before competitors
What is HeyMilo AI?
HeyMilo AI is a recruiting automation tool that conducts candidate screening through phone, video, and web audio interviews. The system uses AI to automatically reach out to applicants, run structured interviews, and deliver scored candidate reports with transcripts to help recruiters assess applicants for volume hiring.
The system positions itself as a recruiter-first solution with scoring algorithms and ATS integration capabilities. HeyMilo offers multilingual support and various interview formats, giving recruiters flexibility in how they screen candidates. The tool generates structured data outputs that sync with existing applicant tracking systems.
HeyMilo targets companies doing volume hiring across various industries, with particular focus on roles that require systematic screening processes. Their multi-channel approach means recruiters can choose between phone calls, video interviews, or web-based audio depending on the role type and candidate preferences.
The system aims to replace manual first-round screening by automating outreach, interview delivery, and candidate evaluation, then surfacing qualified applicants to recruiters with scoring metrics and interview recordings.
What is Classet?
Classet is an AI phone screening service built for high-volume hiring in retail, hospitality, healthcare, and skilled trade roles. The core product is Joy, an AI voice recruiter that conducts structured phone interviews with candidates within seconds of them submitting an application.
Joy operates 24/7 and contacts candidates immediately via phone call, which matters because 64% of applicants apply outside normal business hours. The system conducts conversational voice interviews that verify basic qualifications, answer candidate questions about the role during the call, and flag knockout criteria without requiring scheduling coordination or recruiter availability.
After each screening, recruiters receive full interview transcripts, audio recordings, and structured summaries that sync into 100+ ATS systems including Greenhouse, Workday, Lever, and Bullhorn. The integration requires no engineering work and launches in days.

We built Classet after working at Bluecrew, where we saw the same bottleneck repeatedly: recruiters drowning in applicant volume, spending nights and weekends on repetitive phone screens while candidates never heard back. Joy handles that screening layer so recruiters can focus on actually hiring qualified candidates.
Interview Format and Candidate Accessibility
HeyMilo offers multi-channel interview options, including phone, video, and web audio. Candidates can complete structured interviews on the web or mobile through voice or video, giving recruiters flexibility in screening methods. This works well for staffing agencies and corporate environments where candidates have reliable internet access and time for screen-based interactions.
The video and web audio components require candidates to have stable connectivity, a quiet environment, and the ability to focus on device-based interactions. For roles requiring multilingual support beyond English and Spanish, HeyMilo provides broader language coverage.
Joy takes a phone-only approach that removes technical friction entirely. Candidates simply answer a call within seconds of applying. No app downloads, no video setup, no Wi-Fi requirements.
When Sears Home Services switched from written assessments to Classet's voice interviews, completion rates jumped from around 50% to over 70%. The reason was simple: technicians could talk rather than type. This same pattern holds across high-volume hiring: retail workers between shifts, restaurant staff on breaks, healthcare workers after rounds, and warehouse workers on the floor can complete phone interviews without screens or a stable internet connection.
Joy operates 24/7, so a candidate who applies Sunday morning gets interviewed immediately, not scheduled for the following week when recruiters return.
Speed of Candidate Engagement

HeyMilo sends automated invitations via SMS, WhatsApp, or email after candidates apply. Candidates choose when to complete their screening interviews at their own pace. This asynchronous method provides flexibility but relies on candidates checking messages and taking action, which can delay engagement by hours or days.
Classet calls candidates within seconds of application. Joy reaches applicants before competing offers arrive, which matters in markets where qualified candidates receive multiple opportunities. In skilled trades hiring, time-to-hire exceeds comparable professional positions. When skilled tradespeople are scarce and ghosting is common, timing determines whether you talk to candidates at all.
One Classet customer described the reality: if candidates apply to 10 companies, they only talk to the first two that respond. The immediate phone call reaches people when interest is at its peak. Waiting for candidates to notice email invitations or find time for scheduled sessions means competing with whoever called first.
Workflow Complexity and Ease of Setup
HeyMilo requires setup and training to fine-tune questions and scoring metrics. The system provides customizable scoring rubrics, detailed candidate reports with evidence summaries, and configurable interview agents that can be tailored by role. Recruiters can customize screening rules and assign different weights to various skills. This depth of customization works well for staffing agencies presenting candidates to external clients or large recruiting teams managing complex hiring workflows. The trade-off is that setup requires defining scoring criteria, configuring knockout logic, and managing multi-channel engagement preferences.
Classet focuses on simplicity for users who need to start screening immediately. Joy Sync connects with over 100 ATS systems without engineering work. Implementation completes in days, not weeks.
The system offers proven interview templates for common roles, such as warehouse, HVAC, and construction. You can deploy these templates without configuration. For custom needs, you can create your own scripts with tone, questions, and FAQs, but no engineering of the scoring rubric is required.
Most small and mid-sized businesses hiring at volume don't have dedicated HR departments. The owner or office manager handles hiring alongside running operations. For organizations hiring frontline workers at scale, we removed the workflow complexity that enterprise tools require. You get applicants, Joy calls them immediately, and you see qualified candidates.
Security and Compliance: Why the Auditor Behind the Badge Matters
AI phone screening handles sensitive candidate data at scale: names, phone numbers, work history, and recorded conversations. For companies hiring frontline workers at volume across retail, hospitality, healthcare, or skilled trades, vendor compliance determines whether you're protected or exposed.
Both Classet and HeyMilo carry SOC 2 certifications. But the details matter.
HeyMilo achieved SOC 2 Type I compliance in April 2025 through Delve, a compliance automation platform. In March 2026, a detailed investigation alleged that Delve systematically generated auditor conclusions before reviewing evidence, used identical boilerplate across hundreds of reports, and relied on certification mills rather than independent CPA firms. Companies that received compliance reports through Delve may face questions about the validity of those certifications.
Classet is SOC 2 Type II certified and audited by Prescient Assurance, an independent, US-based CPA firm specializing in security and compliance attestations for technology companies. Classet also uses OneLeet for continuous security management, a platform built by former ethical hackers that prioritizes real security over compliance theatre — including attack surface monitoring, penetration testing, and device-level controls.
The distinction between Type I and Type II matters for enterprise buyers. Type I tests whether security controls were designed correctly at a single point in time. Type II verifies that those controls actually operated effectively over a sustained observation period (typically 6-12 months). Enterprise security reviews and InfoSec teams routinely require Type II before approving a vendor.
For companies hiring at scale in retail, hospitality, healthcare, or skilled trades, where every interview generates call recordings and candidate PII, compliance determines whether your vendor partnership protects your business or exposes you to audit risk.
Why Classet is the Better Choice
HeyMilo AI works well for staffing agencies and corporate recruiting teams who need video interviewing capabilities, detailed scoring reports to share with clients, and multilingual support across many languages. Organizations with dedicated recruiting teams managing complex workflows may benefit from HeyMilo's depth of customization.
Classet wins for high-volume hiring where phone beats video, speed beats scheduling, and simplicity beats sophistication. Retail workers between shifts, restaurant staff on breaks, healthcare workers after rounds, warehouse workers on the floor, and HVAC technicians on roofs can take a phone call but can't sit for a video interview. When completion rates jump 20+ percentage points by switching to voice, the format matters more than feature count.
Spring hiring season is here, and employers staffing for their busiest months need tools that contact candidates immediately, interview them without friction, and deliver qualified candidates to hiring managers faster than competitors. We built Joy to win when the goal is filling positions before the candidate takes another offer, not generating scoring reports for client presentations.
Final Thoughts on AI Interview Automation
The Classet vs HeyMilo decision depends on who you're hiring and how fast you need to move. Organizations hiring at volume for retail, hospitality, healthcare, warehouse, and skilled trades benefit from instant phone engagement that reaches candidates before competitors do, without requiring video setup or scheduled sessions. Staffing agencies with complex client requirements may prefer HeyMilo's detailed reporting and multi-channel options. We built Joy because businesses hiring frontline workers needed something simpler that just works. Your hiring volume and candidate type should guide the choice more than feature count.
How do I decide between Classet and HeyMilo for my hiring needs?
Choose Classet if you're hiring for high-volume roles in retail, hospitality, healthcare, warehouse, and skilled trades where candidates work with their hands and prefer phone communication. Pick HeyMilo if you're a staffing agency needing video interviews, detailed scoring reports for client presentations, or screening support in languages beyond English and Spanish.
What's the main difference in how candidates complete interviews with each tool?
HeyMilo sends candidates SMS or email invitations to complete video or web-based interviews at their convenience, requiring internet access and screen time. Classet calls candidates within seconds of application for immediate phone interviews that need no apps, Wi-Fi, or scheduling: candidates just answer the call and talk.
Who is Joy best suited for compared to HeyMilo's approach?
Joy works best for retail operations, hospitality venues, healthcare facilities, warehouse operations, and trades contractors hiring frontline workers at scale who need to fill positions fast without dedicated HR teams. HeyMilo fits corporate recruiting departments and staffing agencies that manage complex workflows, need customizable scoring systems, and present candidate evaluations to external clients.
How quickly can I start screening candidates after signing up?
Classet's Joy Sync connects to your existing ATS in days without engineering work, and you can use pre-built interview templates for common roles immediately. HeyMilo requires more upfront setup time to configure scoring rubrics, customize interview agents by role, and train your team on the multi-channel system.
Will switching to phone-only interviews reduce my candidate completion rates?
Phone interviews actually increase completion rates for frontline roles. When Sears switched from written assessments to Classet's voice screening, completion jumped from 50% to over 70% because technicians could talk while working instead of finding time to type on screens.
