There are many different leadership styles: autocratic, democratic, servant, pacesetting, coaching, collaborative, inclusive, compassionate, and more. The NHS prefers that its leaders have a collaborative, inclusive, and compassionate leadership style to deliver the highest quality patient care.
Collaborative leadership is a management practice that brings staff, executives, and managers together and shares information organically. Inclusive leaders are individuals aware of their biases and actively seek out and consider alternative perspectives to inform their decision-making and work more effectively with others. Compassionate leadership involves listening to your colleagues, understanding their challenges, and empathizing with them.
Since the NHS is vocal about its leadership style on its website, you want to focus on describing your leadership style as one or all of the three styles. You want to show the interviewers you have the leadership qualities they seek in a Band 6 nurse.
