Dang...this doesn't sound good!
From my interview (10/15), it was obvious that they are changing and bettering the MMI's every single time due to feedback that they get. So, all the september interviewees, as well as some october ones were the Guinea pigs. However, they mentioned during my interview day that it didn't matter because you would be graded based on how well you performed compared to everyone else that day.
This doesn't make sense...so either they lied and everyone who interviewed early is totally at a disadvantage, or they have a certain number of open slots per interview group invited and it's the luck of the draw depending on who else is interviewing with you. I don't like either of the options.
Regardless of which one it is, Davis isn't doing a very good job of making me like them right now.
