Well let us start with correcting your English here:

Are you afraid of a job interview? I am really afraid of a job interview in English.

It's difficult. You have to speak in another language, you have to explain why you are good at the job, and you should try to be a charming personality all in one time. I am reasonably good in English, but even I froze up during an interview once. You could start with making some notebook entries in which you answer standard questions like: What is your image of your career in 5 years? Standard stuff they always ask. Then we will correct it here.

I think it's very natural to be a bit nervous about job interview. Although you can overcome your frightening by training. Some rehearsals with a friend or teacher can bring you more confidence.

BTW, you can even apply for some job you are not really want to take, but just to exercise your interview skills.

I suggest you might rehearsal before your interview . Setting several possible questions you could be asked and trying to answer these questions before your interview . 

I do a lot of interviews in English of people who are non-native English speakers.  Here are some of my suggestions:

1.  A lot of times people mis-understand the question.  If you have any doubts about what is being asked, ask for a clarification, or restate the question back to the interviewer. 

2.  If the interview is in person, sometimes drawing a picture or diagram is good.  I had an inteview once that was not going well at all, but the person stopped to draw a picture and demonstrated his understanding of the process so well that we wound up hiring him.

3.  When you are speaking, pause occasionally so that if the interviewer needs to break in, they can.  If you're nervous, you might just keep speaking for 10 minutes straight.  Don't.

4.  Rehearse your answers to common questions.  Over and over.  And then over again.

Thank you for your recommendations for job interview and support, guys. It is very important for me now)
