Whiteboarding
Screen sharing
60-minute sessions
System design interviews.
Deep architectural discussions with real-time whiteboarding. See how senior engineers actually think — without booking yours.
One round, on the whiteboard.
A calibrated problem, a shared canvas, and senior-level probing.
A real problem, calibrated.
A production-scale design challenge, matched to the role's seniority.
Same problem and rubric across the role.
Scored like a design review.
Structured rubrics that capture what matters in system design.
Architecture
Component choices, service boundaries, and data flow.
Look for · coherent systems
Scalability
From 1K to 1M users — caching, sharding, horizontal scale.
Look for · growth thinking
Trade-offs
Consistency vs availability, latency vs throughput — argued out loud.
Look for · reasoned decisions
Failure handling
Failure modes, redundancy, graceful degradation.
Look for · plans for the bad day
Where it fits.
Screen first. Design deep. Your engineers meet only finalists.
System design questions.
The direct answers before you bring us a role.
Do candidates actually whiteboard?
Yes — a real-time collaborative canvas with shapes, connectors, and text. Candidates draw the architecture while explaining their reasoning, like any design session.
How senior is the probing?
The AI digs into scalability, failure modes, trade-offs, and edge cases the way a senior engineer would — and its follow-ups react to what's actually on the board.
Does this replace our architecture round?
For screening, yes. Candidates schedule instantly and interview the same day, 24/7 — your senior engineers only meet the ones who've already shown they can design.
Can candidates ask clarifying questions?
Yes. It's a two-way conversation — candidates probe requirements and constraints before committing to a design, just like a real session.
Best for.
Senior & staff engineers
Technical architects
Engineering managers
Platform & infra leads
Teams that can't spare senior engineers for every screen.
Senior-level screens, without your seniors.
Watch a design round run end to end — whiteboard, probing, scorecard.
