While your interviewer can see that you have employee management in your experience from your resume, this question is allowing you to really get into detail about what experiences you have in working through a performance appraisal process with your staff in the past. While being open and honest in your experiences, try to highlight your ability to use fair judgement in writing performance appraisals and highlight any technologies that you've used to help manage the performance of your team. As well, don't hesitate to discuss any of the difficult conversations you've had in the past with your staff as UBA Prestige Bank will look to you to be an effective part of this process as their next Branch Manager.
