First of all, it would be different if you are IS or OOS. But I'll give you both since you didnt mention it.
For 2014, (the most recent data) showed that they had 2240 OOS applicants and interviewed 333 of them. 15% chance of receiving one OOS.
IS shows 253 applications with 152 interviews showing a 60% interview rate if you are IS.
The numbers show that it is very competitive to get an interview OOS and it is not that competitive if you are IS.
Now acceptance rates of interviewees show that out of 333 people OOS, they accepted 222. 66.7% of OOS applicants who interviewed got in.
For IS out of 152 people 84 got in. This shows only a 55.2% acceptance rate.
From those stats, I would say as an OOSer it is easier to get in provided you get an interview.
If you are wondering why they accept more than their class size, remember people do drop acceptances. Amount accepted are not equaled to the amount enrolled.
Hope this helps and good luck on your interview.
