Being invited to a job interview means you have passed the first test, and you are probably able to work in the company in the near future. There is something you can do to prepare for the interview before the day comes.
You should spend some time researching the company. You can get the information by having a look at their website. Knowing a lot about the company makes you feel confident when you are asked about the company in the interview. And it also allows you to ask questions.
You can go to the company the day before to find out how long the journey will take. You should also plan another way of arriving there so that if something unexpected happens (for example. a traffic jam), you can still get there on time.
Decide what to wear for the interview and get the clothes ready. You don't have to buy a new suit. Cleanliness and tidiness are the most important thing to remember when you are choosing clothes.
If all these preparations have been done,you can put all the information together to make sure that nothing has been left out when you go to the interview.
