It's important to demonstrate that you have broad commercial awareness and keep up to date with developments in the business and financial press, but you should also be prepared to show that you're following the audit industry specifically and be ready to discuss it in detail.

Make sure you're able to discuss these issues, and their impact on firms in the industry.
