"A call center supervisor demands the communicative and service-oriented skills of a customer service representative, but the motivational and organizational skills of a leader. In an interview context, expect to be asked about your management style, comfort level with speaking to difficult customers, and ability to multi-task between duties. Be prepared to role-play a scenario where you must overcome a negative customer or diffuse a team conflict. Employers are ultimately looking for candidates who can oversee their operations successfully, so make sure you emphasize your understanding of what it means to lead and keep others on task."
Did not find any of the questions difficult. Usual behavioral based questions. Although others told me they were asked why a round cover is put on holes in the street, instead of square or rectangle.
