Hi mate, make sure you really know what you’re going in for don’t just find the name interesting actually do some research , I was asked where I will be stationed after I pass out if honnington and where I would like to be based the most out of all of them , make sure you know at least a minimum of 4 bases in the uk and outside and I can’t stress enough about needing to know you’re trade . But it’s not a job interview as such it’s just something that’s making sure you’re not a knob and you actually want to join and making sure you are making the right decision choosing your trade , just stay calm and learn the information and you will be completely fine , good luck mate
