• Firstly prepare a good CV or resume with proper use of English. The most important thing that provides a basic idea about you is your resume. Keep it on the first page of your file.
• Arrange all your marksheets and passing certificates in an order starting with latest qualification on top.
• If the profile demands extra curricular efforts, then include those certificates also.
• Don't mention those things that you are not aware of.
• Put on formal clothes while attending it.

Good luck !
