Interactive tools — issue trees, whiteboards, spreadsheets — appear in context, mirroring real interview and work environments.

Framework

Main Branch

Is model quality degrading (model drift)?

Level 1

Is input feature distribution shifting?

Level 2

User session length distribution shifted: median 4.2 min → 1.9 min after app redesign

Level 2

Training data covers pre-redesign sessions only (data cutoff: 8 months ago)

Level 1

Are offline metrics (NDCG, MAP) correlated with CTR drop?

Level 2

NDCG@10 declined from 0.74 to 0.61 in shadow evaluation against live traffic

Level 2

A/B hold-out shows 2019-era collaborative filter outperforming current model by 14%

Main Branch

Is the feature pipeline producing stale or incorrect signals?

Level 1

Are real-time behavioral features stale?

Level 2

User affinity scores update every 6h but browse events lag 4.8h on avg (SLA: 1h)

Level 2

23% of requests served with affinity scores >12h old during peak load

Level 1

Is null/missing feature rate rising?

Level 2

Null rate for "recent-purchase" feature: 3% → 19% after payment-service schema change

Level 2

Feature monitoring alerts: 0 triggered (alerting threshold set to 25%)

Main Branch

Is serving infrastructure introducing latency or fallback behavior?

Level 1

Are p99 latency spikes triggering fallback to popularity-based ranking?

Level 2

Model inference p99: 180ms → 420ms after canary deploy of v3.1 (SLA: 200ms)

Level 2

38% of requests falling back to non-personalized popularity baseline during peak hours

Sharpen Your Judgment

Learn which questions are worth asking, which problems actually matter, and how to prioritize what to investigate first.

Churn is rising — I'd invest in a retention program.

Feedback

After each session, get scored across multiple dimensions with specific, actionable feedback that feeds back into your skill profile.
