"When interviewing for an account owner position, be prepared to speak to your skills in communications, marketing, and client relations. Employers will be interested in your ability to create long lasting relationships with clients and generate sales for a portfolio of accounts. Your interviewer may test your abilities with a role play question, so be prepared to give a mock sales pitch to a difficult client."
Not difficult , but crazy questions and rapid fire round in F2F. For a salesperson rapid questions is a cake walk !!
Make sure don't give the hiring manager an ego buzz kill with good answers especially if you a product of early promotion and not aged enough for the role
