These are literally the kind of LLM interview questions most candidates wish they had seen earlier.

A curated list of 50 LLM interview questions - shared by Hao Hoang.

What’s covered:

Fundamentals: → Tokenization and why it matters → Attention mechanisms in transformers → Context windows and their tradeoffs → Embeddings and initialization → Positional encodings

Fine-tuning & Efficiency: → LoRA vs QLoRA → PEFT to prevent catastrophic forgetting → Model distillation → Adaptive Softmax for large vocabularies

Generation & Decoding: → Beam search vs greedy decoding → Temperature, top-k, top-p sampling → Autoregressive vs masked models

Advanced Concepts: → RAG (Retrieval-Augmented Generation) → Chain-of-Thought prompting → Mixture of Experts (MoE) → Knowledge graph integration → Zero-shot and few-shot learning

Math & Theory: → Softmax in attention → Cross-entropy loss → KL divergence → Gradient computation for embeddings → Vanishing gradient solutions in transformers
