Frequently Asked Questions about AI Engineer Interviews

What is the difference between an AI engineer and an ML engineer?

ML engineers typically work on training and deploying custom models (PyTorch, TensorFlow). AI engineers primarily integrate pre-trained foundation models (LLMs) into applications via APIs. The AI engineer role emerged with the LLM era and requires strong software engineering skills more than deep ML research knowledge.

Do AI engineer interviews test math and statistics?

Less than traditional ML roles. You're expected to understand concepts like embeddings, similarity search, and tokenization at an intuitive level, but deep mathematical derivations are rarely tested. Focus on practical system design and implementation.

What is RAG and why is it important for AI engineers?

RAG (Retrieval-Augmented Generation) is a pattern where you retrieve relevant context from a knowledge base before sending it to an LLM. It lets you give LLMs up-to-date or proprietary information without fine-tuning. Most production AI applications use some form of RAG.
