Hi everyone,

"Dear Sir/Madam,

First of all, let me introduce myself as ABC - graduated BBM (Bachelor of Business Management) in Miranda Institute of Management Studies (MIMS) - India. Your company caught my attention with much enthusiasm. So I would like to come to you with a background that you will find unique and distinctive among your typical applicants.
Over the past 2+ years, I have identified myself as a high sense responsibility and hard working. I am ready for new challenges and opportunities with my practical skills and appreciate experience with my education.
Some of qualifications outlined above are representative of the value I offer the company and are more fully outlined in the enclosed resume.
