The CV is not just a piece of paper with your career details on it, written in English. NO! It is a Sales Letter. Just like a sales letter for a product lists the products benefits and it needs careful crafting to achieve the job of your dreams.
Effective CV Tips: A Career Objective right at the beginning of your CV should write about how your skills will benefit the school or educational institution 'IF' they hire you. What you want to do in your career, life, your goals and ambitions are of least interest to the recruiter, so keep these out.
Including hobbies is big NO. "I like playing the violin, football and making friends". Such statements are okay for a frsher or internship CV, but not for a professional one.
