Exchange Order Book

This question tests whether you understand how markets organize live trading interest, including the difference between buy side demand and sell side supply, and how orders are displayed by price and share quantity. In investment banking interviews, this kind of topic is common because sales and trading roles require fluency in market structure, order flow, and the basic mechanics of how securities are quoted and traded. Candidates are expected to know not only what kinds of orders appear in the book, but also how the exchange ranks them and why that matters for matching buyers and sellers in an active market.
