Tell Me About Yourself? Interview Tips for HR Interview, How to answer this question? - February 2013

TELL ME ABOUT YOURSELF

This is the most commonly asked question in interviews... To start the interview and the interview will proceed by the way we answer this question.

This question is always like "Ball in one's court".. one has to be very true to oneself to answer.. never bluff..based on my experience.. start with your personal details like your name and where u r from... then instead of telling about your family members jump to academics.. start from your highest qualification.Here u tell them about any extra curricular activities. (Tech or Non tech) like member of ISTE, tech. paper presentation. Be very descriptive while telling about your extra cir. act. during your graduation.

Since this is often the opening question in an interview, be extra careful that you don't run off at the mouth. Keep your answer to a minute or two at most. Cover four topics: early years, education, work history, and recent career experience. Emphasize this last subject. Remember that this is likely to be a warm-up question. Don't waste your best points on it. They don't want to know about your family, your last vacation, your hobbies, your religious beliefs, that you like the Cubs, or that you are a proud member of AA
