1⟩ Why this industry?
What is it about the work environment that appeals to you? Perhaps you're applying to be a retail manager because you particularly like the idea of working in a store. Or maybe you're applying to be a construction site manager and you've always been an outdoors type. It will be particularly impressive if you can talk about the challenges and developments facing the industry.
If you're applying for role in transport you could talk about rising fuel costs, for retail you could talk about the role of online shopping and for construction you could talk about sustainability, for example. That would show that you've got business sense and are commercially aware, a crucial skill for a manager.
