Original post by IkarussHi Grace, welcome to the forum and first of all, best of luck with your application. What are you applying for?
You ask specifically about the selection interview and, if I'm reading it right, looking for a model answer to a specific question. If you want to know about the format of the OASC interview, then fire away, many people on here can give you the up to date gen - my first OASC interview was 1976 and the last in 2002 (while serving!), but I'm pretty sure it hasn't changed much.
If you actually do want model answers, then I'm afraid you're out of luck. The whole point is that they want to see a. what YOU know about an increasingly complex world (World and UK) and b. what YOUR opinions are on a topic that they'll choose.
So you have to have a very good knowledge of current affairs and be able to articulate your thoughts about them. That doesn't mean they expect you to know everything about everything, but you would struggle badly if you hadn't spent a good 6 months immersed in the current news. Being of a certain age, I have a solid understanding of world news, but I have to keep it topped up all the time, or it would be quickly out of date.
When I did OASC in 76, the Cold War was at at its height, and the world was pretty much black and white. Not so now, it's incredibly complex and nuanced. The OASC boarding officers may pose tricky questions as you've indicated, but there are no right or wrong answers, if there were do you not think someone, somewhere would have made it happen. All you can do, is understand who the players are in a geo-political setting, understand their aims and try to work out how they can achieve them. I assume you're talking about the Middle East; I thought I understood it about 15 years ago when I was running a pre OASC workshop for my station, but events have proved me, the USA, the UK , Russia and all other regional states, wrong.
So just get into your current affairs, plan what topics you want to talk about, and brainstorm your ideas with family and friends. The TSR community are also friends, so if you want to bounce ideas off anyone here, feel free.
It's not easy, but the best things aren't. Work hard at it, and you'll succeed, trust me. I did, and I ain't no rocket scientist.
Regards
Ikky
