AI Onsite Interview Preparation:
Your Final Round Guide
Onsites are marathon interviews—4-6 sessions in a day testing everything.
Learn how to prepare for and perform across all rounds.
Onsite Interviews
Are Exhausting and High-Stakes
4-6 hours of back-to-back interviews with different formats and interviewers.
You need to stay sharp across coding, system design, and behavioral rounds.
Different interviewers have different styles—you need to adapt quickly.

Meet Your Mentor
My aim has been the same for years: become a world-class AI engineer. Every career move I've made has been measured against that.
I started as a software tester on a $500/month internship in the Netherlands. Taught myself to code, learned to ship real systems, and worked my way to Senior Engineer at GitHub.
Then I left GitHub. I joined an AI research lab as Member of Technical Staff, where I currently build products for secure AI monitoring.
The cohort draws directly from my real experience so you can make progress fast.
I run this special cohort with only a few people because hands-on work with me is what it takes to bring you to become a world-class AI engineer.
Real Results

AI Engineer
Built and deployed his portfolio piece, then landed the AI role
"The coaching played a huge part in my success. I focused on AI fundamentals, the certification path, and soft skills like professional writing. Having access to expert guidance gave me confidence during interviews and helped me feel I was on the right path.
I built my own platform (simple but functional) and deployed it on AWS. I used it in my portfolio and showcased it during interviews. The way complex topics were explained, especially the restaurant analogy for AI systems, really stuck with me. Focusing on doing the basics well was absolutely essential."

Frequently Asked Questions
What does a typical AI onsite interview schedule look like?
Common format: (1) 1-2 coding rounds (45-60 min each), (2) 1-2 system design rounds (45-60 min each), (3) 1-2 behavioral rounds (45-60 min each), (4) Lunch with a team member (30-60 min, usually informal). Some companies add: hiring manager round, technical deep dive on your background, or team presentations. Total: 4-6 hours. Ask the recruiter for the specific format.
How should I prepare the week before an AI onsite?
One week out: review system design patterns, practice 2-3 coding problems daily, prepare behavioral stories. Two days out: light review only, no new material. Day before: rest, prepare logistics, review company info. Day of: eat breakfast, arrive early (in-person) or test setup (virtual), stay hydrated. Don't cram the night before—sleep matters more than extra practice.
Is the lunch round really evaluated in AI onsites?
It varies by company. Some use it purely for culture fit assessment—they're asking: 'Would I want to work with this person?' Others are truly informal. Either way: be pleasant, ask good questions about the team and work, don't complain about anything, and treat it professionally. It's rarely a technical interview, but social skills matter. When in doubt, be curious and friendly.
How do virtual AI onsites differ from in-person?
Virtual onsites: (1) Shorter breaks between rounds (plan bathroom time), (2) More Zoom fatigue—energy management is harder, (3) Technical issues can disrupt flow, (4) No lunch round usually, (5) Harder to read room. Compensate by: testing all tech beforehand, having backup plans, taking standing breaks, keeping water nearby, and being extra clear in communication since body language is limited.
How do I recover from a bad round during an AI onsite?
Bad rounds happen to everyone. Recovery tips: (1) Don't dwell—each round has a new interviewer with no context, (2) Take your full break time, (3) Do a quick reset ritual (deep breaths, water, bathroom), (4) Remember that passing doesn't require perfection, (5) Focus forward on what you can control. One weak round rarely sinks an otherwise strong onsite.
How long does the full AI onsite process take?
The onsite day itself: 4-6 hours. Total time including prep: 2-4 weeks of preparation is typical. After the onsite: 1-2 weeks for decision. If you're interviewing at multiple companies, stagger your onsites if possible—doing multiple in one week is exhausting and hurts performance.
I've signed up for cohorts before and dropped out. How is this different?
It probably isn't, and you should hold the money. Most cohort dropouts are people who couldn't articulate what they were shipping when they signed up. That's why the consult exists, and why I turn down most applications. If we get on the call and you can't tell me what you'll have shipped at the end of week 8, I'll point you to the AI Native Engineer community until you can.
I'm not pivoting careers. I want to build a product. Does this still work?
Yes, the cohort works for people shipping their first serious AI system whether the goal is to land a senior role or to launch a product. The shipped system serves both equally well.
Do I need prior AI experience?
You need to be able to code in Python or TypeScript. Complete beginners can follow the classroom they get access to before the cohort sessions to come in well-prepared.
What does it cost?
It's a four-figure investment that we discuss during the 30-minute consult, alongside whether the cohort is the right fit for your project.
Can I do this while working full-time?
Yes, most attendees do. The live session is one Tuesday a week and the async work fits around your existing schedule, as long as you can carve out roughly 6 hours a week.
I accept those who have the highest chance of success.
In the 30-minute call we discuss your goals and whether you are ready for the program.
