This is just a quick post to those who can feel like there's no hope, or no school will take a chance on them.
I am an older candidate with a very unrelated background looking at full-time MBA programs in the US.
At the start of my application journey, I had no idea what I was getting into, so though I knew i had good scores, I wasn't sure where that placed me. I wanted to go to a great school to make a total career change from the best possible starting point.
SO, I wrote in to some consultants on websites. One, who I will not name though she is very well known, looked at a post I made on another site and basically told me that my GMAT score (710, was wondering if I should retake - I did and scored 750) was the least of my worries in apps. She wondered what schools would want from me being that I am older, my gpa was too low, and my background is not standard. Basically she made it sound like I didn't have much of a chance at any school I wanted to attend.
It was just a random comment on the internet, albeit for someone I hoped to receive constructive criticism from (not just outright dismissal), but it still hurt. I started to doubt my chances, but pushed ahead regardless. Others were also less than optimistic, telling me to focus only on one year or EMBA programs. (This seems to be their standard for anyone over 30, alas) I knew that wasn't the right path for me, so again, I kept going, though with more and more doubts and nerves.
This week I was accepted to CBS. I am so happy. I have some other interviews coming up, but at the very least, I am into a great M7 and am really proud. That was my goal.

This is just a reminder - those who are commenting on your profiles / essays / career aspirations are only giving their opinions. No matter how well known they might be, how many posts they've made here or on p&q, you are in charge of your future. Keep the faith. Stay the course and do your best. Sometimes great things happen even when THEY say they wont.
