More often that not, job interviews give people the jitters. Your stomach may be tied in knots for a long time before the interview even starts – perhaps even days before it’s scheduled. It’s perfectly natural and common to have these feelings, and you can calm your nerves by reminding yourself that you already passed the first screening. This means the company wants to meet you, so give yourself some credit.
An interview will go well if you act like yourself and if you and the interviewers get along well. That said, be yourself. If you try to be someone or something you are not, it will likely be obvious and turn out poorly for you. If you present yourself honestly and you and the interviewer don’t click, maybe it’s not the right company for you. Don't sweat it.
