Senior Judgment, Screened Before the Whiteboard
Scalability, reliability, and the trade-offs between them. A scenario-based design assessment finds real architectural judgment before you schedule the panel.

Design Interviews Are Expensive. Screen First
A proper system design interview takes a senior engineer's hour and a candidate's nerves, and half the time it reveals within ten minutes that the conversation shouldn't be happening. The signals were checkable earlier: does this person reason about failure modes, know when a queue buys you something, understand what consistency actually costs? Those judgments have testable structure long before anyone draws boxes on a whiteboard.
QuikQ's System Design template presents senior-level scenarios: a system under growth, a reliability requirement, a trade-off with no free option. Candidates choose and justify approaches through structured questions, weighted-scored because design mistakes are the expensive kind. Use it to decide who earns the whiteboard hour.
Structured Design Signal
Scenario-Based Questions
Realistic systems under realistic pressure, with defensibly better and worse choices.
Scalability Judgment
When to shard, when to cache, when the honest answer is that you don't need to yet.
Reliability Thinking
Failure modes, degradation strategies, and what breaks first at 3 a.m.
Trade-Off Awareness
Consistency versus availability, latency versus cost. The questions live where the tension is.
Senior-Calibrated
Rated hard and weighted-scored, designed to differentiate at the staff level.
An Hour, Not an Afternoon
Sixty minutes of structured signal before anyone books panel time.
How It Works
Three steps, start to finish
Adapt the Scenarios
The template's design scenarios adjust to your domain: consumer scale, B2B reliability, or data-heavy.
Screen Senior Applicants
Candidates take the hour asynchronously. Anti-cheat and timing keep it comparable.
Spend Panels Wisely
Scores tell you who reasons about systems, so whiteboard hours go to real conversations.
Where It Earns Its Hour
Staff+ Pipelines
Filter senior applicant pools before committing panel-interview capacity.
Full-Stack Depth Check
Runs as the weighted design section inside the Full-Stack Engineer template.
Promotion Evidence
Structured design judgment as one input to senior engineering promotions.

Frequently Asked Questions
Can system design really be tested without a whiteboard?+
The judgment layer can: recognising failure modes, choosing appropriate patterns, and weighing trade-offs all have structured, scoreable forms. The whiteboard conversation still matters; this decides who it's worth having with.
What level is the assessment aimed at?+
Senior and staff-level engineers. The scenarios assume production experience, and the difficulty is calibrated to spread out strong candidates rather than confirm basics.
Can I adapt scenarios to my architecture?+
Yes. Edit them directly or describe your domain to the AI, then review its drafts. Domain-flavoured scenarios read as more credible to senior candidates too.
How does this fit with the full-stack test?+
The Full-Stack Engineer template includes a lighter design section. This standalone assessment goes deeper, suited to roles where architecture is the primary job.
Is it free?+
Yes, fully. Template, weighted scoring, and anti-cheat included.
