Alex vs. HeyMilo

HeyMilo is an AI interviewer: it runs the screening conversation over voice, video or phone, scores it, and puts candidates into an async self-schedule flow. Alex owns the whole process. It coordinates real calendars instead of handing out a link, adds WhatsApp and SMS to video and phone, writes back to 100+ ATS platforms, and carries SOC 2 Type II with certified CPRA and TCPA. Choose HeyMilo for a light first-round screen. Choose Alex when coordination, reach and audit evidence decide it. Here's the side-by-side.

What each tool actually is

HeyMilo is an AI interviewer. It conducts the screening conversation over voice, video or phone, scores it, applies behavioral integrity signals with an ID check, integrates with 15+ ATS platforms, and puts candidates into an async self-schedule flow.

Alex is an AI recruiter. The distinction is scope: as well as running the interview over video, phone or WhatsApp — with SMS carrying invites, reminders and reschedules — Alex coordinates scheduling against live calendars and verifies integrity against a threshold you set per role from 0 to 100, with signals broken out by analysis type in the candidate report, separate fraud scoring, and an optional document-and-selfie ID check. Results sync into 100+ ATS platforms. Interviewing is one step; the handoffs around it are where volume hiring loses days.

Where HeyMilo fits

A lighter deployment. Async self-scheduling needs no calendar integration project and no availability rules. There's less to configure, and nothing that picks up the coordination work after the screen.

Voice, video and phone. Three ways into the interview, none of them the messaging channel most candidates actually answer on.

If an async first-round screen is your only constraint, HeyMilo will do the job.

Where Alex pulls ahead

Coordination, not a self-schedule link

Alex manages the whole process step by step, coordinating against real calendars: it detects time zone from area code, respects blackout periods so calls and texts don't land at 6am, offers real mutual availability when a human interviewer is involved, and handles reschedules without a recruiter mediating.

Volume funnels rarely stall with the interview. It's usually the days between a passed screen and a booked follow-up with a recruiter copying times into email. A self-schedule link solves the first booking; coordination solves every one after it.

Channels a candidate will answer

HeyMilo's interview runs over voice, video and phone. All three still ask the candidate to take a call or open a session on a device, at a moment they've set aside.

Alex adds WhatsApp and SMS, and that changes who finishes. A WhatsApp message gets read when a call from an unknown number does not. Across much of the world it is the default phone. SMS then covers the outreach layer — invite, reminder, reschedule — which is where funnels leak before a conversation ever happens. Compare the two tools on completion rate for your hardest-to-fill role, because abandonment concentrates precisely there.

Type II, and compliance that's certified

HeyMilo's SOC 2 is Type I, a point-in-time review of control design. Alex's is Type II, which tests whether those controls operated over a period of time. This is the version enterprise security teams insist on, and months of audit work, not a naming convention.

What to test in a pilot

Run both tools on the same requisition and compare:

• Completion rate on your hardest-to-reach role, not your easiest
• Days from application to a scored interview, and days from passed screen to a booked next round
• Share of interviews flagged for integrity review, and the false-positive rate
• Whether your ATS is supported natively, and whether results arrive without a manual export
• Which SOC 2 report type each vendor can send today

The verdict

Choose HeyMilo if async self-scheduling fits how your team books interviews and a light first-round screen is all you need. Choose Alex if the delay in your funnel is coordination rather than interviewing, if candidates need WhatsApp to reach you, or if SOC 2 Type II is a hard requirement.
