Too long. You generally interview with the Account Manager, Director, and COO or CEO. They like to have you interview in one day, which means you can be there for awhile waiting for each person to have time to interview you. They'll make you wait in the conference room until they're ready. Poor planning and time management. If the Account Manager likes you they'll prep you to be successful with the Director and CEO/COO. They'll tell you what you need to say to get hired.
