in real time

Ray doesn't just ask questions. It listens, evaluates the answer, and decides whether to probe deeper or move on — just like a seasoned interviewer would.

Interview rounds

Three rounds.
One system.

Each round surfaces a different kind of signal. Pick the ones that matter for the role you're hiring.

ROUND 01
Screening

15 minutes of focused project discussion. Validates whether candidates actually did what their resume says — ownership, end-to-end thinking, and real decisions made under pressure.

15 min fixed Project discussion Adaptive probing JD-grounded
Screening probe example "Walk me through a product you owned end-to-end. What were the hardest trade-offs you made?"

→ opening question · grounded in JD: "end-to-end ownership"

"You said you 'owned' the backend — did that include deployment and on-call? What broke first?"

→ probe triggered · verifying actual ownership vs stated ownership

✦ 2 targeted probes generated from a single answer

ROUND 02
DSA

Calibrated to experience level and complexity tier. Not just "did they solve it" — but why this approach, what are the trade-offs, how does it scale under real load.

Entry → Expert Easy → Super hard Fresh questions Reasoning probes
DSA probe example "Given a stream of events, find the top K most frequent in the last N seconds."

→ main question · hard · senior level

"You chose a sliding window — what's the memory complexity at 100K events/sec?"

→ trade-off probe · triggered by candidate's approach

✦ Probes generated from candidate's specific solution path

ROUND 03
System design

Open-ended design matched to your company stage and tech stack. Probes failure modes, scale bottlenecks, and real architectural decisions — not just the happy path everyone rehearses.

Stage-calibrated Stack-aware Failure mode probing Scalability focus
System design probe example "Design a notification system for 10 million users. Walk me through your architecture."

→ main question · enterprise stage

"Your queue falls 5 minutes behind during peak — what's your degraded mode?"

→ failure probe · triggered by mention of message queue

✦ Adapts based on company stage selected by recruiter

What makes it different

Built for signal,
not just screening.

🎯

Adaptive Probing

When a candidate says something interesting — or evasive — Ray digs deeper. Every answer shapes the next question.

"Why that approach specifically?"
🛡️

Anti-Gaming

Pulls from a repository, external sources, and AI-generated questions. Candidates can't prep for it. Your bar stays honest.

JD-Grounded

Skills can be faked. Lived experience can't. Every question ties to actual responsibilities from your job description.

100% calibrated to your role
🧠

Context Memory

Screening context flows into the full interview. No repetition, no starting over — just deeper evaluation every step.

Early feedback

What teams are saying

"We cut first-round screening time from 3 hours to 20 minutes per candidate. The probing questions caught things we'd have missed in a normal screen."

SR
Shruti R.
Engineering Lead, Series B startup

"The system design questions adapt to the candidate's answers — it's the closest thing I've seen to an AI actually interviewing instead of just quizzing."

MK
Marcus K.
CTO, B2B SaaS company

"Finally something that checks if candidates actually built what they claim. The ownership probes are spot-on for finding founding engineers."

AP
Ananya P.
Recruiter, early-stage fund portfolio

"Set up the first interview in under 5 minutes. Had qualified candidates ranked by Monday morning without a single scheduling email."

JL
James L.
Founder, Pre-seed startup

"The scored reports are genuinely useful — not just a transcript dump but an actual recommendation with the reasoning spelled out."

FAQ

Common
questions

Everything you need to know about Ray.

Ray uses a three-source question strategy: a curated repository, dynamically fetched questions from external sources, and AI-generated questions unique to each session. Even if two candidates get the same base topic, follow-up probes branch based on their specific answers — making every path unique.

The adaptive probing makes gaming extremely hard. Even if a candidate memorises an answer, the AI immediately follows up with "why that approach specifically?" or "what would break first at scale?" — questions that require genuine experience to answer credibly. Surface-level rehearsed answers get exposed quickly.

Ray reads your JD and suggests the right configuration — company stage, role seniority, experience level, and complexity tier. Each setting adjusts what questions are asked and how deeply the AI probes. A founding engineer interview at a 5-person startup looks very different from a staff engineer interview at a large company.

Yes — when a candidate moves from screening to a full interview round, Ray loads the screening report and uses it to calibrate. If the candidate showed strong system thinking in screening, the full round pushes harder. If there were gaps, those areas get revisited with more targeted questions.

Voice-first. AI questions are read aloud using natural text-to-speech. Candidates speak their answers, which are transcribed in real time. This creates a more natural interview feel — and often surfaces how candidates think under actual conversational pressure, which typed forms don't capture.
