First of all, business schools do not choose a person, they choose a profile. You have to give a clear picture of who is and what you want to do through your profile. So work on your story and your communication and believe in it. This is essential.
Secondly, don’t hesitate to ask for advice. Everybody believes that they know education because they went to school. However, business education is something very specific. From the outside, we do not have a very good perception of the school, of what they can offer, or their contacts. It is easy to be fooled by their advertising and marketing. That’s why I strongly suggest that you work with professionals. I was lucky enough to find Dr. Hubert Silly and the MBA Center team, who have been able to help me throughout the application process. I strongly recommend serious candidates to work with such people.
