"Businesses depend on their business managers to oversee the operations of a department to ensure that goals are being met and productivity is consistent. In an interview, expect to cover questions about large accounts you may have managed, your previous experiences in business, and how you handle conflict or stress. In addition, you may be asked to explain how you validate data integrity or to even provide a sales pitch for their company."
Is that all you've prepared for your powerpoint?
Yes because there isn't much revealed in the brief required. It's pretty much running blind.
