Hi,
I'm happy to help you as it is my area of expertise. I will start by the last question. I know the dilemma about the age and MBA. The average age is always around 28 years old. so you are above the average. It means that it is high risk to get rejected but I have seen other succeeded to join their schools (not many but there are few). When you apply to any adcom in any school, they won't exclude reject you directly. They will give you opportunity till the end of process. Pls read the following link to have the experience of the applicant.
indian-it-male-age-35-13-interview-4-admits-2-full-scholarships-219953.html#p1696523After you read the link, you need to focus on and search for word 'lack', it appeared twice in his post. it means you need to be understand the real competition ( the pool of applicant you come from, GMAT score, schools you apply to and your goals). When you find the second 'lack', it was about essays. At this age, the adcom expects you to have really precise goals and know it in details. Make it strong and clear. It is not enough to say that you have dreams to work in supply chain. You need to elaborate more. Give yourself time and dig deep in yourself. Lacking to express your goals in this age will give impression that you are not mature enough. It might be accepted somehow from younger applicants. The second issue you need to be realistic about schools selection. When it comes to supply chain, we have good schools to choose from MBA focused on supply chain (MIT, Ross, Darden, Kelley, Eli broad, Ohio, Krannert (1 & 2 years MBA), Carlson, Smeal, Georgia Tech, Arizona and others). Although not highly ranked MBA, Tennessee is known for powerful supply chain MBA.
Never heard that Tuck or Duke are known for supply chain. However, some schools offer courses for supply chain inside operation management concentration but it is not known for supply chain. I attached you USs news ranking for supply chain MBA
If you decide to do an Msc in supply chain, you have good program such as Ross and Ohio, UT Dallas and others. Those are STEM Program. Be careful do not assume every MSc in supply chain is STEM. A good example is Krannert MSC in supply chain. It is new but not yet STEM.
For your info, STEM program now enjoy up to 3 years and if you continue higher degree you will enjoy other 2 years. 2 months ago, new rules were announced.
I hope it helps
