"Walk me through how you'd design a distributed notification system for 50 million users. What are your first-principles assumptions?"
Your Interview Twin
"I'd start by separating concerns: a message broker like Kafka for ingestion, a fan-out service for delivery routing, and push/email/SMS adapters at the edge. My first assumption is that at-least-once delivery is acceptable..."▌

Real Output
This is what your session actually looks like.
Two exchanges from a real Interview Twin session — generated from a backend engineer's CV targeting a senior role.
Interviewer
"Walk me through how you'd design a notification system for 50 million users. What assumptions would you make first?"
Your Interview Twin
"I'd start with two assumptions: at-least-once delivery is acceptable for non-critical alerts, and we can tolerate up to 5 seconds of latency outside push. From there, I'd separate ingestion from delivery — Kafka as the message bus, a fan-out service per channel, and edge adapters for push, email, and SMS. Each adapter has its own dead-letter queue..."
Interviewer
"Tell me about a time you pushed back on a stakeholder deadline. How did you handle the pressure?"
Your Interview Twin
"At my previous company, the VP wanted to ship in 2 weeks what I estimated at 6. Instead of just saying no, I put together a written breakdown: three failure scenarios with probability and business impact. I proposed a phased plan — core feature in 3 weeks, full scope in 8. I framed it as risk management, not capacity. He agreed to the phased approach and we hit both dates..."

Answering: System Design Round
Listen to your AI twin answer your real interview — built from your CV.
Most candidates fail because they've never heard their own answers out loud. Interview Twin reads your CV, builds an AI version of you grounded in your real experience, then runs it through a full senior interview. The output is a 10–20 minute audio podcast — your twin answering the exact questions your target company asks, with pushback included. You listen. You hear what's weak. You fix it.
- Personalized to your exact resume + job description — no generic questions
- Choose your interview type: Behavioral, System Design, Technical, Leadership
- Pick your accent (US / UK / India), difficulty, and session length
- Hear your simulated answers out loud — spot filler words, weak reasoning, missing depth
- Regenerate any session in seconds with a different angle or higher difficulty
"The Interview Twin is terrifyingly accurate. It grilled me on race conditions in a way no human interviewer has. I walked into my actual Google loop feeling like I'd already passed."
— James C., Senior SWE · Google
Your Interview Loop
Once you know your gaps with Interview Twin —
Train for the full marathon. Not just the first mile.
Most candidates practice one question at a time. Real onsites are 4–6 rounds of relentless, cumulative pressure. Interview Day replicates the full loop — multiple rounds, multiple AI interviewers, every round delivered as a full audio session you can replay. Listen to how your twin handled round 3. Hear where you slipped. Fix it before the real day. Stop being surprised by something you could have already lived through.
- Custom 3–5 round loop: Behavioral → Technical → System Design → Leadership, in sequence
- Different AI interviewer persona each round — simulates real variation across interviewers
- Company DNA analysis: AI researches what your target company actually asks
- Full audio + transcript for every round — review exactly where you slipped
- Train for fatigue: most candidates ace round 1 and crumble by round 3

"Interview Day was harder than my actual Microsoft onsite. By the time I got to round 4 in real life, I felt like I'd been there before. I got the offer."

"I ran 5 Interview Twin sessions before my Google L5 loop. The system design questions were almost identical to what they asked. I walked in feeling like I'd already done this."

Marcus T.
Staff Engineer · Microsoft
"I heard myself say 'um' 12 times in my first Interview Twin session. That was the wake-up call. By session 3, I was crisp. Nothing else exposes this like hearing yourself answer."
