Read question
LLM Eval & OpsIntermediate

How Do You Build an Eval Suite for an LLM-Powered Feature?

Walk through building a systematic evaluation suite for an LLM feature — from test case design to automated metrics and regression tracking.

Read question
Prompt EngineeringIntermediate

What Strategies Do You Use to Reduce Hallucinations?

Walk through a layered approach to reducing LLM hallucinations — from prompt-level techniques to retrieval grounding and output validation.

Read question
Prompt EngineeringIntermediate

How Would You Design a Prompt for Structured Data Extraction?

Design a prompt that reliably extracts structured data (JSON, tables) from unstructured text — handling missing fields, ambiguity, and format errors.

Read question
RAG & RetrievalIntermediate

How Do You Handle Chunking Strategies for Different Document Types?

Compare chunking strategies for different document types — PDFs, code, HTML, and tables — and learn when each approach works best.

Read question
RAG & RetrievalIntermediate

Design a RAG Pipeline from Scratch

Walk through designing a production-ready RAG system covering document ingestion, chunking strategies, embedding models, vector search, and LLM generation.

Read question
RAG & RetrievalIntermediate

How Would You Evaluate Retrieval Quality in a RAG System?
