600+ LLM, Agentic AI, RL Interview Practice Tests - LLM Pretraining, FSDP, MCP, LangGraph, ReAct, MOE, GRPO, PPO, RLOO

Our expertly crafted practice tests are aligned with the most recent breakthroughs in AI, ensuring both comprehensive coverage and focused depth on high-impact areas. These tests are tailored to assess your understanding across a wide spectrum of cutting-edge topics including:

· LLM Pre-Training: Data curation strategies, scaling laws, decoding techniques, KV caching, learning rate schedulers, adapters, and fully sharded data parallelism (FSDP).

· LLM Architectures & Optimization: Advanced components like Flash Attention, Mixture of Experts (MoE), Switch Transformers, and evaluation tools such as LLM Judges and Self-Instruct frameworks.

· Fine-Tuning & Alignment: Techniques such as GRPO, PPO, DPO, DAPO, REINFORCE with Leave-One-Out (RLOO), RLHF, and ReAct-style tool-augmented finetuning.

· Specialized Frameworks: LangGraph for agentic AI workflows, Model Context Protocol (MCP) for dynamic tool integration, and DeepSeek models with multi-stage training pipelines including reinforcement learning and distillation.

· Model Compression & Inference: Knowledge distillation, quantization (including advanced methods like 2-bit packing), and test-time scaling for cost-efficient deployment.

· Retrieval-Augmented Generation (RAG): Deep understanding of the RAG triad—context relevance, groundedness, and answer relevance—and their role in evaluating truthful and context-aware responses.

· LLM Evaluation & Tooling: Techniques for systematic evaluation of model outputs, reward modeling, rejection sampling, and human-in-the-loop strategies.

· Infrastructure & Deployment: Insight into modern GPU architectures and performance optimization for pretraining and inference workloads.

Additionally, the course includes real-world interview questions from top-tier tech companies, making it ideal for aspiring AI engineers aiming to master LLMs, agentic systems, and RL-based fine-tuning at scale.
