| 1. During the interview, look at the interviewer even if you are very nervous and shy. Communication between eyes is important in an interview. 2. First, do some research on the company. What does the company do? Does it make or design things? Does it provide a service? If the company has a website, visit website and find out a little more about the company. 3. You should also prepare one or two questions. At the end of the interview, it is usual for the interviewer to invite you to ask some questions. It can be a simple question like "When will you let me know if I've been successful? " If you do not have any questions, the interviewer may think that you are not very interested in the job. 4. Before you go into the interview room, knock on the door. It is one of the ways to show that you are polite. Then you will probably hear someone say "Come in!" and you will know it is time to go into the room.. | |
