It is not unusual to feel nervous when going for an interview. It shows that the interview matters to you and that you want to do well at it. The question is: how do you stop nerves getting the better of you and ruining your chances of getting that dream job.
The first thing to remember is that an interview is a two way process. It is as much about you interviewing them as them interviewing you. You need to think about the questions you want to ask the interviewier to see if this is not only the right role for you but also the right environment. After all, you are going to be spending a large part of your waking hours working at the company you eventually decide to go to. A few questions you could ask include:
!) If you offer me the role, what would you expect me to achieve in my first three months?
2) What is the culture of the company?
3) Why do you enjoy working here?
The other thing to remember to conquer your nerves is that the people interviewing you are people just like you. They get up in the morning, they play with their children, they go to bed at night. If you take them out of the work place in your mind and think of them doing ordinary things, it can stop them seeming quite so terrifying.
I hope this helps. Good luck with the job hunting!!
