To prepare to your interview we advise to do the following:
- complete and review practice interview before you start your "Real" interview
- dress appropriately
- put glass of water on the desk in front of you (in case you get thirsty)
- have a notebook and a pen/pencil beside you to make some quick notes, that you could use during your answer (to sneak peak if you said everything that you wanted to say, but DO NOT read the whole answer from the notes)
Be yourself and you will do great!
Best of luck with your interview!
