Be candid and personable. Answer questions based on what you believe, rather than what you think the right answer is.
It goes without saying but be yourself. Approach the interview as if its a conversation rather than a Q&A.
Sparkes prioritises people, so a lot of your interview will be about you and your experiences. Have examples ready of times when you demonstrated leadership, solved a conflict, etc., etc.
The questions that you ask towards the end of the interview may be more important than you think as they can really show your personality and leave the interviewers with a strong impression of who you are. Consider including a question that helps you get to know the interviewers.
Be confident, and personable. Don't just give answers you think the interviewers want to hear - they will see right through that. Don't be afraid to ask for clarification if you didn't understand the question!
