Evaluator AI
Score your design before the interviewer does.
Submit your diagram and get an overall score, five sub-scores and a SWOT, with fixes ranked by priority.
Evaluator AI example
Executive Summary
A solid first pass on a rate limiter: the token-bucket core is right, and the design names its failure modes instead of hiding them.
SWOT Analysis
Strengths
- • Token bucket chosen over a fixed window, so bursts are handled fairly.
- • Redis called out explicitly as the shared counter store.
Weaknesses
- • No plan for what happens when Redis itself is unavailable.
- • Per-user and per-IP limits are not distinguished.
Opportunities
- • A local cache in front of Redis would cut the hot-path latency.
- • Sliding-window counters would smooth the edge-of-window burst case.
Threats
- • A single Redis instance is a single point of failure for every request.
Key Insights
Redis is a single point of failure
Every check depends on one Redis instance. A replica or a fail-open policy belongs in the design.
Token bucket is the right primitive
It allows short bursts while still enforcing a steady average rate, which fits a public API.
Actionable Improvements
Add a Redis fail-open policy
Decide, and state, whether requests pass or fail when the counter store cannot be reached.
Separate per-user and per-IP limits
A shared limit lets one bad actor exhaust a whole IP range's budget.
Cache hot counters locally
A short-lived local cache in front of Redis cuts the common-case round trip.
Interviewers Perspective
What They Look For
- • A clear choice of limiting algorithm, stated and justified.
- • An answer for what happens when the counter store is down.
Mistakes to Avoid
- • Treating the counter store as always available.
- • Skipping per-user versus per-IP limits entirely.
Potential Follow-ups
- • How would you shard the counter store across regions?

Instead of a hunch, a scored report
Every field mirrors the model's real response, not a marketing mock-up.
Angle 1
A blank rubric in your head → Five sub-scores, named
Scalability, reliability, performance, security and maintainability each get their own score, not one vague verdict.
Angle 2
Strengths and gaps you have to guess at → A SWOT built from your diagram
Strengths, weaknesses, opportunities and threats come back specific to what you actually drew.
Angle 3
A list of everything that's wrong → Fixes ranked by priority
Suggested improvements carry a priority so you know which one to fix first.

What Evaluator AI will not do
- It will not replace a real interviewer's judgment on the day.
- It will not catch a flaw the diagram never shows.
- It will not turn one score into a hiring decision.

Questions about Evaluator AI
What counts as a diagram?
Any architecture sketch: boxes and arrows, a whiteboard photo, or an exported diagram from your tool of choice.
How is the overall score calculated?
It's built from five sub-scores: scalability, reliability, performance, security and maintainability, each judged against your diagram alone.
What's in the SWOT?
Strengths, weaknesses, opportunities and threats, each grounded in a component or a flow your diagram actually shows.
Are the fixes specific to my diagram?
Yes. Every suggested improvement names a component and carries a priority, not a generic checklist.
How is this different from Interview Research?
Research builds a citation-backed brief on how a company engineers. Evaluator AI scores the diagram you bring to the interview.
