Concurrency vs Parallelism Quiz
Test your understanding of concurrency, parallelism, threads, processes, the GIL, and safe use of async database sessions.
Concurrency: Race Conditions & Synchronisation
Go beyond the basics: race conditions, locks, semaphores, deadlocks, async patterns, thread safety, and when to use multiprocessing vs threading vs async.
Claude Code Best Practices Quiz
Test your understanding of context management, verification loops, plan mode judgment, permissions strategy, and cost control in Claude Code.
Decision Trees Quiz
Test your understanding of Gini impurity, entropy, recursive splitting, overfitting control, and feature importance in decision trees.
Multi-Agent Orchestration Quiz
Test your understanding of supervisor/worker decomposition, handoffs, shared state versus isolated workers, pipeline-vs-barrier synchronization, cost multiplication, and when a single stronger model beats N agents.
Memory Systems for LLM Applications Quiz
Test your understanding of the memory taxonomy — short-term, long-term, episodic and working memory — what belongs in each, eager vs retrieval-triggered loading, how memory fails (staleness, injection, bloat, conflicts), and how CLAUDE.md implements the taxonomy in practice.
MCP Servers and Subagent Orchestration Quiz
Test your understanding of the Model Context Protocol, MCP authentication and managed MCP, MCP trust boundaries, subagent context isolation, subagent naming and background execution, parallel fan-out tradeoffs, git worktree isolation, and multi-agent review pipeline design.
Claude Code Fundamentals Quiz
Test your understanding of the agentic loop, built-in tools, permission modes, and configuration scoping in Claude Code.
LightGBM Quiz
Test your knowledge of LightGBM parameters, learning rate trade-offs, regularization, leaf-wise growth, and gradient boosting fundamentals.
System Design Basics Quiz
Test your understanding of fundamental system design concepts: scalability, availability, caching, and load balancing.
GANs and Face Generation Quiz
Test your understanding of the GAN-vs-diffusion-vs-autoregressive comparison, the minimax objective and non-saturating loss, the mode-collapse/vanishing-gradient/instability failure ladder and their named fixes, StyleGAN's mapping network and style injection, latent-space controllability, and evaluation with precision/recall for generative models.
Case Study: Visual Defect Detection on a Production Line Quiz
Test your grasp of factory-line visual inspection: one-class anomaly detection when defects are rare, reconstruction vs. memory-bank approaches, pixel-level PRO/AUROC evaluation, the escape-cost-vs-scrap-cost decision policy, edge inference constraints and the per-SKU model-zoo problem.
Case Study: Virtual Try-On for Fashion E-commerce Quiz
Test your grasp of the virtual try-on case study: the catalog-vs-personal mode split, the GAN-vs-diffusion architecture argument, garment-agnostic person representation, garment-fidelity evaluation, selection bias in return-rate analysis, and the precompute/cascade scaling patterns.
Case Study: Synthetic Training Data for Computer Vision Quiz
Test your grasp of the internal-flywheel synthetic-data engine: why realism is never the success metric, the approach ladder from simulation through conditional diffusion, model collapse and the real-data-anchor filter, train-on-synthetic-test-on-real evaluation, and the telemetry-to-promotion system design.
Case Study: RLHF / Preference-Tuning Platform Quiz
Test your grasp of the RLHF/DPO platform-engineering capstone: preference data collection, Bradley-Terry reward modeling, reward-hacking detection, RLHF vs. DPO vs. RLAIF trade-offs, rollout-generation-dominated RL compute, and release-gating discipline for a monthly-cadence model.
Case Study: Super-Resolution and Photo Restoration Quiz
Test your grasp of the edge-vs-cloud super-resolution case: the perception-distortion trade-off, degradation modelling, RRDB/ESRGAN generators and the relativistic discriminator, evaluation beyond FID, and the edge-vs-cloud scalability story.
Case Study: Generative Fill Quiz
Test your grasp of the inpainting/outpainting/object-removal case study: the GAN-vs-diffusion cascade thesis, mask conditioning and seam blending, why FID alone isn't enough, crop-around-the-mask scaling, data and mask-distribution engineering, and the content-provenance and licensing requirements this case forces.

Test your grasp of platform-scale synthetic-media detection: the provenance-vs-detection distinction, the DFDC's unseen-generator generalization trap, the defence-in-depth cascade, frequency-domain GAN artefacts, reach-weighted review policy, and the continuous-retraining arms race.
Case Study: AI Product Photography at Scale Quiz
Test your grasp of the AI product-photography case study: why the design segments before it generates, product-region invariance as a hard gate, batch-offline scaling versus the interactive cases in this track, cheap-first routing and template reuse, and the disclosure/provenance requirements this case forces.
Text-to-Video Generation Quiz
Test your understanding of the compute argument for latent diffusion, LDM's temporal-plus-spatial compression, temporal attention/convolution and 3D DiT patches, video-text data scarcity mitigations, Fréchet Video Distance, and the video-specific inference pipeline stages.
