Frameworks

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

Framework

Main Branch

Is the regression in the application service layer?

Level 1

New code path introducing O(n²) complexity?

Level 2

Flame graph shows 60% CPU in nested loop (added in PR #4821)

Level 2

p99 correlated with request payload size — O(n²) signature

Level 1

Thread pool exhaustion or blocking I/O?

Level 2

Thread pool utilization: 94% (up from 41% pre-deploy)

Level 2

Synchronous Redis call added to critical path — no timeout set

Main Branch

Is the regression in the data access layer?

Level 1

Database query plan changed (missing index, stats stale)?

Level 2

EXPLAIN shows full table scan on orders (87M rows) — index dropped in migration

Level 2

DB CPU: 88% vs 32% baseline; connection pool wait: +210ms median

Level 1

Cache hit rate degraded after deploy?

Level 2

Redis hit rate: 61% (was 94%) — key schema changed, cold start in progress

Main Branch

Is the regression caused by infrastructure changes?

Level 1

Network latency or instance type change?

Level 2

Deploy rolled new instance type: c5.2xlarge → c5a.2xlarge (AMD); 12% lower network bandwidth

Level 2

Cross-AZ traffic increased 40% — RDS replica not updated to same AZ

Level 1

Config drift — timeout or concurrency limits changed?

Level 2

Max concurrent DB connections reduced from 200 → 50 in new env config

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.
