Start with the present and tell why you are well qualified for the position. Remember that the key to all successful interviewing is to match your qualifications to what the interviewer is looking for. In other words you must sell what the buyer is buying. This is the single most important strategy in job hunting.

So, before you answer this or any question it's imperative that you try to uncover your interviewer's greatest need, want, problem or goal.
To do so, make you take these two steps:
Do all the homework you can before the hr interview to uncover this person's wants and needs (not the generalized needs of the industry or company)

As early as you can in the interview, ask for a more complete description of what the position entails. You might say: "I have a number of accomplishments I'd like to tell you about, but I want to make the best use of our time together and talk directly to your needs. To help me do, that, could you tell me more about the most important priorities of this position? All I know is what I (heard from the recruiter, read in the classified ad, etc.)"

Then, ALWAYS follow-up with a second and possibly, third question, to draw out his needs even more. Surprisingly, it's usually this second or third question that unearths what the interviewer is most looking for.

You might ask simply, "And in addition to that?..." or, "Is there anything else you see as essential to success in this position?:

This process will not feel easy or natural at first, because it is easier simply to answer questions, but only if you uncover the employer's wants and needs will your answers make the most sense. Practice asking these key questions before giving your answers, the process will feel more natural and you will be light years ahead of the other job candidates you're competing with.

After uncovering what the employer is looking for, describe why the needs of this job bear striking parallels to tasks you've succeeded at before. Be sure to illustrate with specific examples of your responsibilities and especially your achievements, all of which are geared to present yourself as a perfect match for the needs he has just described.

("A strong company needs a strong person." An employer will get faster return on investment because you have more experience than required.)

(Refer to accomplishments. Everyone has had a few of these pressure situations in a career. Behavior-related questions aim at assessing a candidate's character, attitude, and personality traits by asking for an account of how the candidate handled certain challenging situations. Plan for such questions by making a list of the desirable traits relevant to the needs of the industry or prospective employer and by preparing some job-related stories about your experience that demonstrate a range of those traits and habits of conduct. Before answering the questions, listen carefully and ask any clarifying questions you think necessary. Tell your story and conclude by explaining what you intended your story to illustrate. Finally, ask for feedback: "Does this tell you what you need to know?")

(Remember, you're talking to a prospective employer, not your best friend. Don't dredge up a catastrophe that resulted in a personal or corporate failure. Be ready for this question by thinking of a story that has a happy ending - happy for you and your company. Never digress into personal or family difficulties, and don't talk about problems you've had with supervisors or peers. You might discuss a difficult situation with a subordinate, provided that the issues were resolved inventively and to everyone's satisfaction.)

(Relate past success in accomplishing the objectives which are similar to those of the prospective employer. )
