----------
Before an LLM can understand a single word you type, it must first convert that text into tokens. Most beginners assume LLMs read language the way humans do โ but that assumption leads to a lot of confusion in interviews and in production. In this video, we break down tokenization from the ground up in a structured interview Q&A format built for AI Engineer and GenAI interview preparation.
We cover what tokenization is and why raw text cannot be fed directly into a model, the complete pipeline from text to tokens to numbers to model output, the difference between word-level and subword tokenization, and a deep dive into Byte Pair Encoding โ one of the most common follow-up questions interviewers ask after tokenization. Every section is explained simply with the exact strong answer you should give in your next interview.
