Bharathy,
Resume writing is an art and can be very effective if portrayed in a right manner. Well, basically we need to follow a few points when we make a resume:
1- Not more than 2 pages.
2- Present your objective in a very effective manner; it should tell the company what you can give, not what you want.
3- Your skills and knowledge.
4- Your professional details; it is important to give details of only two organizations at max, not all if you have changed many.
5- Write your responsibilities briefly; don't forget to include Key Result Areas (KRAs), and never mention processing work.
6- In achievements, ensure they are quantified; using numbers is more effective.
7- Education should be summarized, starting with the highest degree.
8- Include special learning experiences like other professional courses or job-related seminars attended, not everything.
9- Personal Details: include your Date of Birth, Gender, Marital Status, Languages known, and Passport Details.
Resume formatting is also very important. Use spaces, good fonts, and ensure the content is readable without being overly dense.
