It is much simpler...

Don’t know how many of us shall agree with the above statement. But, I am sure; it is possible to do so with a clearer understanding of the process, expectations and obviously with a lot of common sense. The purpose of any Personal Interview is to gauge the self management abilities, including the important ability to present ideas clearly and persuasively to others.
My simple suggestion to all is not to look at the process of Interviewing from the prism of a Question-answer session.
In this post, we shall focus on Personal Interviews. The idea behind this exercise is to provide you practical tips that might give you a sense of purpose, direction and clarity while developing effective responses/answers to some expected questions/situations. Remember, the focus is on using these ideas as inputs, not as out puts or ready-to-use answers. We shall learn how to be our natural self, rather than being looked as a Programmed Robot.

Hence, use the following ideas/techniques/suggestions as just inputs .And there is nothing like a model answer or Best answer...You have to simply manage yourself...your skills/Attitude...and the expectations of the Interviewer well.
Always remember that one size does not fit all. And more importantly, we need to showcase that little’ Extra thing’ that makes us different from others, which can other wisely be called as ‘Unique representation ‘.Your responses must reflect  of your uniqueness, personal beliefs, values and hence, lets  avoid giving stereotyped answers.
Go thru the following Questions along with the Tips:
