Prepare for a job interview. Good preparation will make the process less stressful and you will be more calm and confident. 
When applying for a job, you should be able to present yourself, your work experience and your key skills. Questions during the interview may, also relate to the new job; "Why you are applying?" or "What you expect from your new job?". It is therefore important to prepare the answers in advance.

Haven't received any interview invitations so far? Maybe you need to improve your CV.
