Commercial awareness starts with a simple idea: before you can advise a business, you need to understand how it works. That means knowing how it makes money, who its customers are, what could threaten its revenue, and how it protects itself from those threats.
Most candidates treat commercial awareness as "reading more business news." That is the input — not the skill. The skill is being able to look at any business situation, identify what matters commercially, and explain what should happen next.
A company announces it is acquiring a competitor. Business knowledge is knowing the deal value and the parties. Commercial awareness is understanding why the deal makes sense, what risks the buyer is taking on, whether the price reflects those risks, and what the lawyers need to check before the deal closes.
The distinction most candidates miss: Firms are not testing whether you read the FT. They are testing whether you can think like someone who advises businesses for a living. The question behind every commercial awareness exercise is: "If this were your client, what would you tell them?"
