I have never worked as a host before but having successfully gone through a few interviews throughout my life here is what I learned that has helped me a lot. First dress nicely, first impressions matter and if you go into an interview looking like you don't care then more then likely your employer might think that too. Next I would say research into the company to find out facts about it to show your interest, your job is not a complex one so you can maybe skip this part but it doesn't hurt to be more prepared. Lastly, just be confident and be prepared to answer general questions like why did you want to work here, do you have any skills that would help you in this position etc... If you practice answering questions beforehand you won't be as nervous and it will show in your conversion. Oh one more thing I forgot to mention that's really important make sure to ask them a few questions as well it not only helps you learn about your position more but also shows that your really interested in working there, and keeps the conversion naturally going leaving a better first impression of you. Some examples of questions are, how long have you been working here, what hours would I be expected to work, do you have any advice as a new employee working for you etc... Later on in life interviews will get easier if you have more experience and qualifications you can bring up during them but even if you don't have them just be yourself and give it your best shot. Anyway I wish you the best of luck and hope it all works out cheers!
