I agree with researching the place you're interviewing for @KaiRoe - it helps to know what the business/department/organisation is about.
My tip is to reflect on your previous experiences - what are the situations you thrive in? what are the strengths people see in you?
If you've had work and/or volunteer experience, think about what you were recognised for, skills you developed, challenging situations and positive feedback. Use this information to guide you when answering questions. It is also good to provide examples of different scenarios you've come across, how you dealt with it etc. Thinking of some examples beforehand is helpful!
