Why should I hire you?
Your requirement is to hire a fresher. But your question is that why should you hire me from the choice of others. I could reason this. Your best choice is to hire me because I have the ability to put all my effort & work on that once I get committed to a particular task.
I would also like to learn more from the work that I do, so that I could think for a solution to a problem associated with it. Being a positive attitude person I can prove that I will serve the best of your company.
