Female Coordinator Question:

While answering this question, don't simply say that I love to work with people and that is the reason I am into human resource. This is the most common answer and moreover something which makes the interviewer burst into laughter. This answer easily makes them understand that you are saying this just to get the job.
A better way would be to identify some work areas that an human resource coordinator has to perform in his daily routine and relate them to your interest. A possible answer could be, I liked to be a part of the recruitment team which can identify right people and put them into right places. An employment into recruitment slowly developed into a full fledged human resource profession.
