"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."
Explain a time when you did not agree with your director about a policy?
Policies are in placed for a reason, agreeing is not necessary but voicing your opinion and getting understanding helps to ease acceptance of the policy.
There’s been many times where this was a issue, I find the best way to address a director is alone and personal just voicing my honest opinion from a logical perspective but also seeking to understand the directors course of action. Allowing ones self room to comprise has always helped parties on both ends of the spectrum to keep progressing the company.
