AI interview platforms compared: what to look for in 2026

TL;DR: AI interview platforms fall into three categories: video recorders with AI analysis, chatbot-style text interviews, and full voice AI that actually conducts the conversation. For UK care hiring, voice AI (like Lily) consistently outperforms the others because the phone call is where the real signal lives.

The three categories

1. One-way video interview with AI analysis

The candidate records themselves answering pre-set questions. AI analyses language, facial expression, or tone. Common in corporate hiring, rare in care.

Pros: scales, no scheduling
Cons: poor candidate experience, limited signal, heavily criticised for bias, no conversation

2. Chat / text-based AI interview

The candidate messages back and forth with a chatbot. AI asks structured questions, extracts answers.

Pros: cheap, scalable
Cons: slow, text-heavy, misses candidates who don't chat in detail, poor fit for care worker demographic

3. Voice AI phone interview

AI calls the candidate on the phone. Real conversation. Structured questions. Recording and transcript.

Pros: fastest, highest candidate satisfaction, best signal, fits how care workers actually want to engage
Cons: higher build cost for the vendor

Lily sits in category 3. It's the category with the highest satisfaction scores and the strongest signal on care-relevant criteria.

Why voice works for care specifically

Three reasons.

Care workers apply on mobile. They're not sitting at a desk to record a video. A phone call is their native channel.

Care work is conversational. The questions that predict success — situational judgment, values, tone — are best answered in natural speech.

Speed wins. The fastest provider to call wins the candidate. A video interview invite takes hours or days for a candidate to get round to; a phone call is now.

What to check in any AI interview vendor

Does it actually call the candidate, or does it send them a link and wait?
Can I see every question it asks?
Can I audit every score with evidence?
Does it accept diverse accents accurately?
Is there a clear route to human review?
Is compliance (eDBS, RTW) handled inside the same platform?
Does it produce a CQC / Ofsted-ready audit trail?

Frequently asked questions

Do candidates refuse to do AI interviews?

Rare. 91% rate the Lily experience positively. Most prefer it to waiting weeks for a human call.

Is this legal under UK GDPR?

Yes, with candidate notification, human review, and audit trail. All built in.

Does Lily do video?

Not currently. Our customers hire care workers — the phone is a better channel for this workforce. Second-round interviews are usually done by the manager in person or on video.

Can I use Lily alongside another ATS?

Yes. Lily can sit on top of an existing ATS or replace it.
