A timely reminder from BOOTWA - generic questions on these types of forums are fine, but if you attempt to gain an unfair advantage by sharing specifics, then this will be viewed in a very dim light. Remember, you are meant to be demonstrating the core values of a prospective Naval Officer, honesty and integrity are key in this.
There is little to be gained from knowing previous questions or presentation titles, questions are tailored to each interview and the candidate's Branch of Preference. Any pre-prepared answers are quite obvious to the Board and candidates quickly fall apart under further questioning - just be yourself, be honest, enthusiastic and remember you have all done well just to get to this stage, so don't blow it at the final hurdle. We tell all candidates to use the opportunity to 'sell themselves' - be honest, remember why you are here and you will do fine.
I wish you all the very best of luck in your endeavours to join and I look forward to meeting some of you, albeit virtually, over the next couple of weeks.
