"Employers hiring general managers are looking for decisive leaders with previous management experience to oversee a department or division in the company. In an interview, be ready to discuss your ability to lead lower-level managers and implement improvements within the business. General managers may join the company directly through management, so interviewers will want candidates who are capable of forming strong relationships with established employees."
They asked specific questions about the number of sales calls, revenue per territory, etc.
So you need have those ready!
