Hi there -
Thanks for reaching out. Great to see you are already thinking about your school selection and considering both target and reach schools - that's a great way to hedge.
Focusing on the main issue here, your GMAT, have you looked into the GRE? I’ve seen cases where applicants who have struggled with the GMAT have done better on the GRE. While this isn’t the ideal (some adcoms have a preference for the GMAT), almost all of the top schools are taking the GRE and translating the score to “an equivalent” GMAT score. Given that you’ve taken the GMAT twice already, I know this isn’t what you want to hear, but with your current scores you’re at the low end for your targets. In particular, given your current GMAT I’d consider Ross and Darden stretch. To give you some hope, I'm working with someone right now who was never able to break 700 on the GMAT but her GRE translates to a 730....so it's worth a try.
The strongest part of your application is likely going to be your work experience. It’s great to hear that you’re up for a second promotion, and having direct people management will help you stand out. Most importantly, linking your current experience in IT (I’m assuming with some implementation and ops experience) fits very well with your goal of focusing on ops and process improvement. Given your background and goals, Tepper would be a great fit for you.
Your GPA and school are good. They’re not going to hurt you, but likely won’t be a big help either.
Regarding your reach schools, I have worked with clients who have gotten into that level of school with similar GMATs, but they have something else going for them. A very unique background, a killer career, something. Your challenge is going to be in crafting your story and presenting yourself in such a way that you come across as unique and different enough to compensate for other weaknesses.
Hope this helps. I’m happy to chat if you want to discuss your application further.
