From my experience I would suggest the following:

A complete and thorough reflection of WHY an MBA would help you achieve your career goals. Know very well what you wrote in your essays and make sure that you reinforce it in the interview.

WHY MBA? WHY MBA NOW? CAREER GOALS?  ABOUT YOURSELF? (Hint: Show a career progression and also showcase extra curricular activities) WHY XYZ SCHOOL? (Hint: Bring out the match between your goals and what the school has to offer and also what you can contribute and how you can continue to pursue your other interests.) These are all  typical questions and they must be answered VERY VERY well.

If you’re one of the lucky ones to have secured an interview at one of your top choices, don’t be afraid. It’s time to showcase your speaking and presentation skills in a forum that will make or break your candidacy.

Face-to-face communication is losing its cache because of the time we spend networking online.  Ironically, business deals and admissions decisions are often based on how you present yourself in-person, and not necessarily online or on paper. The more time we spend online or using technology, the less time we have to advance our interpersonal communication skills in a “people setting.”  Good admission interviewers are looking for confident, credible, and in many cases, experienced speakers and presenters when they conduct MBA interviews.  Did you know that 90% of face-to-face communication is non-verbal? Experienced professionals and interviewers can see right through uneasiness, ignorance, and fear.  Don’t be one of these interviewees.  The only way to nail the interview is to prepare.
