I believe that a powerful CV is your only chance to make a great impression on recruiters. Even if you don’t have enough qualifications, you should focus on transferable skills that you have (such as leadership and communication skills, ability to make quick decisions or solve any kinds of problems, etc.). If you have volunteering experience, internships, were in a summary school or took part in some educational program, add all of these to your CV and show how proactive and skillful you are. Also, include personal qualities which make you a good match for this position. The most important part, however, is to be confident and have a faith in your success. I you het a rejection, don’t get upset but keep looking.
