AI solutions architect interview on a whiteboard
You draw; the AI interviewer follows the diagram and asks about it. The middle question is a system design sketched on a shared whiteboard, between a decision you would revisit and a latency problem to chase.

The 3 questions the AI interviewer asks
Word for word from the demo. In the demo and in a real interview, the AI also asks its own follow-ups from what the candidate says.
- 1
“Walk me through an architecture decision you made that you would make differently today. What changed your mind?”
What a strong answer shows
- Describes the original constraints fairly, without rewriting history
- Names what changed: scale, cost, team size or an incident
- Shows how the lesson changed the way they make decisions now
- 2On the whiteboard
“On the whiteboard, sketch the architecture of a URL-shortening service: the write path, the redirect path, and where you would put caching. Talk through each component as you draw it.”
What a strong answer shows
- Separates the write path from the read-heavy redirect path, and sizes each
- Chooses a key scheme, such as counter or random base62, and handles collisions
- Places caches deliberately and weighs 301 versus 302 redirects for analytics
- 3
“Your redirect latency doubles overnight. Where do you look first, and what would you expect to find?”
What a strong answer shows
- Starts with what changed overnight: deploys, config, traffic, dependencies
- Reads metrics layer by layer: cache hit rate, database, network, DNS
- Names likely culprits, like a cold cache or slow query, and tests each
What this demo shows
System design is a conversation about trade-offs, and this demo runs it as one. You sketch a URL-shortening service on a shared whiteboard while the AI interviewer sees the diagram as you draw it and asks about it. The AI never draws; everything on the board is yours. Before and after the sketch, it asks about a past decision and a production problem. Employers who run an AI interview for solutions architects set their own design questions and scorecard, and the diagram is saved to the report.

Common questions
Does the AI interviewer draw on the whiteboard too?
No. The candidate does all the drawing, and the AI interviewer sees the diagram as it is drawn and asks about it. What ends up on the board is the candidate's own work, and it is saved to the report.
Can we use our own system design question?
Yes. A real interview uses your questions and your scorecard. Write the design prompt you want candidates to face, add your own follow-ups to it, and the AI generates more from each answer. Each extra coding or whiteboard question is a $1 add-on.
How long does a full architect interview take?
Real Hyrr interviews of 30 to 45 minutes are normal, which leaves room for a design exercise and the discussion around it. Pricing is $6 per completed interview, whatever its length. This demo is cut to about 10 minutes so you can see the format quickly.
