A HeyMilo interview is an AI conversation you do by phone, web audio, or video, usually on your own schedule. HeyMilo says every interview is recorded and scored against the recruiter's rubric, and a trust score checks for outside help. Here's what it scores, what it checks, and how to prepare.
I didn't build Plumlo because AI interviewing is a bad idea. I built it because nobody warns you it's happening, or tells you what it's actually listening for.
HeyMilo does something most AI interviewers don't bother with. It doesn't just claim to be fair, it publishes the actual audit results for anyone to check.
That doesn't make the interview itself any less real, or any less worth preparing for.
Practice the conversation until the conversation is yours.
What HeyMilo actually is
HeyMilo is a conversational AI interviewer built for high-volume hiring, reaching candidates across text, WhatsApp, email, phone calls, and video. Most interviews are on-demand rather than scheduled, so you complete it when it's convenient rather than waiting for an appointment slot.
The interview itself starts with a few knockout questions to confirm basic qualification, then moves into an adaptive conversation that probes deeper into your actual skills and experience, adjusting based on what you say rather than following a fixed script.
Where you're likely to run into it
HeyMilo is especially common in high-volume, frontline hiring, retail, restaurants, healthcare, warehouse roles, and skilled trades, where employers need to screen large numbers of applicants quickly and consistently. It integrates with major ATS platforms including Greenhouse, Workday, and SmartRecruiters, so it often shows up as the first real step after applying.
What HeyMilo is actually listening for
The recruiter sets the scoring rubric for each role, and every answer gets a score with a written rationale and timestamped quotes from what you said. HeyMilo says its scoring is based on what candidates say rather than how they look or sound. It also has its scoring audited on a recurring basis by an independent AI assurance company and posts those results to a public dashboard rather than only claiming fairness privately. That doesn't change what you should do in the interview, but it does mean the scoring is more accountable than most.
Alongside your interview scores, HeyMilo's cheat-detection layer gives the recruiter a trust score built from three signals, according to HeyMilo's own page: voice authentication, detection of AI-generated answers (HeyMilo says its classifiers flag real-time ChatGPT use), and active proctoring for off-screen glances and multiple voices. HeyMilo describes it as an integrity signal that sits alongside your interview scores and doesn't replace human judgment. It doesn't say whether candidates can see their own score. The safest approach is simply answering as yourself, in your own words, without a second screen or anyone feeding you answers.
As of late September 2026, HeyMilo has spun this detection layer out into a standalone product called Red, sold separately to other companies. That's worth knowing: practicing beforehand, saying your real answers out loud until they're genuinely yours, is completely different from using AI live during the interview itself, which is exactly what detection tools like this are built to catch.
Five things to do before your HeyMilo interview
1. Don't assume "on-demand" means low stakes
Being able to complete it on your own time is a convenience, not a sign the evaluation is casual. Treat it exactly like a scheduled interview once you start.
2. Nail the early knockout questions
These come first and confirm basic qualification before the deeper conversation even begins. Know the plain facts about your availability, experience, and qualifications cold before you start.
3. Practice speaking specific answers out loud
Since the conversation adapts based on what you actually say, vague answers tend to get followed up on. Practice saying specific, real examples out loud rather than just thinking through general points.
4. Pick whichever channel you're most comfortable with
Since HeyMilo supports text, phone, and video, choose the format where you naturally communicate best, there's no evidence one channel scores better than another, only that you'll perform better in the one that suits you.
5. Practice with an AI that scores your answers
The closest preparation available is a live simulation built from your actual job description, delivered by voice, and scored on what you actually say. That's what Plumlo does. One session beforehand changes how ready you feel walking into an on-demand interview with no fixed start time to build up to.
What to expect on the day
A message by text, WhatsApp, or email with a link to start when you're ready, or a direct call depending on how the employer has it configured. Expect early qualifying questions first, then a longer adaptive conversation. Complete it somewhere quiet with a stable connection, since it's designed to feel like a real conversation, not a form to fill out.
HeyMilo runs phone, web-audio, and video interviews, plus a timed scenario format with a built-in AI assistant that looks at how you work with AI. HeyMilo doesn't publish which format an employer will pick, so check your invite. Its candidate help guide says to let your browser use your microphone and camera, and lists Chrome, Firefox, and Safari as supported. If you get disconnected, it says to rejoin with the same link and tell the recruiter as soon as possible so they can reschedule.
Common questions
What is a HeyMilo trust score?
It's an integrity score HeyMilo's cheat-detection layer gives the recruiter. HeyMilo's own page lists three signals: voice authentication, detection of AI-generated answers, and active proctoring for off-screen glances and multiple voices. HeyMilo says it sits alongside your interview scores and does not replace human judgment, and it doesn't say whether candidates can see their own score.
Does HeyMilo record you?
Yes. HeyMilo says recruiters get full transcripts and recordings for every interview, along with per-question scores and a written rationale for each score.
Is a HeyMilo interview on camera?
It depends on the format. HeyMilo offers phone, web-audio, and video interviews, and its video format is a two-way video interview. HeyMilo doesn't publish which format an employer will use or whether the camera is required, so check your invite. Its candidate help guide tells you to let your browser use your microphone and camera.
What should you wear to a HeyMilo interview?
It depends on the format. HeyMilo runs phone, web-audio, and video interviews and doesn't publish which one an employer will use, so check your invite. We found no dress code published by HeyMilo. HeyMilo says recruiters get full recordings of every interview, so on a video interview assume you will be seen: a solid-color top, a plain background, and light in front of you work well on camera. On a phone or audio-only interview nobody sees you, so dress however helps you feel ready.
What happens if you get disconnected during a HeyMilo interview?
HeyMilo's candidate help guide says to try rejoining with the same link and to tell the recruiter as soon as possible so they can reschedule.
What languages does HeyMilo support?
HeyMilo's product pages say its phone and video interviews run in 14+ languages, and its blog cites 20+ languages with detection of a language switch mid-conversation.
Does HeyMilo actually check its AI for bias?
Yes, and unusually, it publishes the results. HeyMilo partners with an independent AI assurance company to run recurring third-party bias audits, following requirements like NYC Local Law 144, and posts the outcomes to a public dashboard rather than only making a private claim of fairness.
How does HeyMilo contact candidates?
It reaches out across multiple channels, including text, WhatsApp, email, phone calls, and video, often letting candidates choose whichever channel is easiest for them to complete the interview on.
Is a HeyMilo interview scheduled or on-demand?
Most HeyMilo interviews are on-demand rather than scheduled, meaning candidates can complete them when convenient rather than waiting for a specific appointment time.
What industries use HeyMilo most?
HeyMilo is especially common in high-volume, frontline hiring, retail, restaurants, healthcare, warehouse roles, and skilled trades, where speed and consistent screening across large applicant pools matters most.
