Interview is the process of knowing a person and their qualities. In an interview the interviewer will try and know the best in you, so as to know what profit they can get out of him/her.
Always remember when you are being interviewed there are things which we all have to keep in mind. Ofcourse, there should not be fumbling ( because this way they will get to know that you are not confident of what you are saying), and can result in rejection. Keep an eye contact with the interviewer. You have to be careful about the body presentation. These are some basic things which we have to remember when going for any interview.
My interview was good. The first thing that i really concentrate on is getting the interviewer into conversation, So it should be a 2 way conversation not a question and answer type where the interviewer is asking you questions and you are just answering to them. Instead try and make it 2 way conversation and gain a plus point.
Then it goes on and you will share your previous work experience, your education back ground and then comes the other questions like speaking on a topic and presenting yourself.
Above are the suggestions and personal experience of interview that i have gone through.
