Hi all! Good to see you again!
*waves*
Thanks for the post and the terrific information provided. All of the information here is fantastic and the points raised are absolutely areas new applicants should consider and/or seek to improve.
That said, for those that are considering applying, but don't "check every box", don't get discouraged. I know this was mentioned with respect to GMAT scores, but I would apply that to other areas as well. I suspect that several of us that were successful applicants met a number of the aforementioned qualifications, but perhaps not all. Look at your background and qualifications critically, but don't discount our chances of you are lacking in one area- assess how you may improve it and address to the best of your ability but don't forgo applying altogether if you don't meet all of the ideals. I only say this because I almost didn't apply, but a colleague encouraged me to do so, and fortunately it worked out well.
As mentioned in several comments (and as a mentor told me a year ago), you may not get into your "dream" school, but the school you do attend may be the "right" one for you. I can only speak to my personal experience, but I found that to be true (and couldn't be happier with the school I ended up attending).
