Hi I had an interview back in November and they gave me an offer the week after - they were really friendly and made me laugh loads so don't panic! As for questions - mine were all science-based - I had none about me - and most of the questions stemmed from my work experience and my personal statement so make sure if you've mentioned any cases you've seen at the vets etc. that you can talk about it and why it interested you enough to mention it etc Hope that helped - if you have any other questions just ask
Just relax and try and enjoy it! Smile and try and be yourself, they want to see what sort of person you are! I would suggest knowing your personal statement really well and basic science questions but dont panic if you can't answer something, they will try and point you in the right direction! Good luck! x
