At the most basic level, the panel NEED to know that you can implement the required skills in that specific environment. But, to separate yourself from the other candidates and leave the panel with no questions about your ability to do the job, the panel WANT to know that you can think independently, take control of stressful situations, and convey your ideas clearly and concisely under pressure.
Usually, an interview will begin with a range of competency-based questions (strengths, weaknesses, describe a difficult situation and what you did to overcome it, a time when you have failed and bounced back, these sorts of questions) or technical questions (Can you describe the energy system development you would implement within this sport? Please describe in detail the fundamental requirements of power development and how you would implement these in season?).
Here you will get the opportunity to put your best foot forward, but there is another opportunity to sell yourself. The questions which you get to ask the panel about the role.
When you come to the end of your interview, often you will be offered the opportunity to ask the interview panel any questions. If you aren’t given this opportunity, which would be rare, then politely request to ask a couple of questions before you leave. Don’t leave without taking the chance to sell yourself just that little bit more.
