Sure you do.
1) It's about much more than good numbers.
2) MDApp entries are not broadly representative of the applicant pool, and can also be not an accurate representation of the person. Hey, remember, it's the internet.
3) Many people who have superior numbers are inferior in other areas. Many get in anyway, some don't.
4) Interviews are given to applicants who, on paper, looked to be suitable. Sorry to say, but waitlists and rejections are given to those of them who were judged to be less appealing in person than on paper. Or, some have personality quirks or other issues that interfere with making a good impression. Those who tend to do poorly on interviews can do so consistently on one after another.
Good luck to you guys. Those of you with interviews remaining, do some serious practicing and get professional help to improve your performance.
