part 2....
The more you can prepare likely responses, the less likely you are to be caught off-centre and start (as you say) babbling. You can take notes in with you, a notebook and writing down things they say to you will not go against you, (as long as you say when you go in that you would like to take notes) and you can have bullet points in your book for things you want to make sure you cover in the interview. There is bound to be "do you want to ask us anything else?" at the end, so if you have a list, you won't forget anything, and it shows them you have prepared for the interview, which is good. If you feel yourself starting to flap, stop and take a deep breath and say "I am sorry, I am really nervous as I am really keen to get this job" - an experienced interviewer would rather you admitted it, so they can help put you at your ease. Give yourself plenty of time before the interview, get there early so you can go to the loo and sort yourself out so you are waiting and looking composed (even if you are not!) when they call you. Another point is to dress comfortably but smartly - it does make a difference, if a candidate looks as if they have got ready for an interview, instead of going to the shops, it makes a good impression when you first enter the room. And smile - and good luck, let us know how you get on!
