Prestige of healthcare STEM job for M7 MBA

Hi guys,

I am a medical laboratory scientist who is looking into transitioning into healthcare <abbr title="investment banking">IB</abbr> or healthcare management consulting post-MBA. I am aware how crucial it is to land in the <abbr title="Top 7 MBA business schools">M7</abbr> or their European counterparts ( INSEAD, <abbr title="London Business School">LBS</abbr> , Ox-bridge ) for this endeavor. First of all, I have a 3.9 GPA and a 780 GMAT. My undergraduate institution was not a prestigious one at all. I am curious, however, if my job and employer would be considered "high" prestige by adcoms especially when compared shoulder to shoulder with <abbr title="investment banking">IB</abbr> and  consulting guys. I work for Stanford Health Care as a medical laboratory scientist. It is an in-demand healthcare and STEM job at one of the most highly regarded healthcare systems in the US. Would this job and employer be impressive enough for <abbr title="Top 7 MBA business schools">M7</abbr> adcoms? Also, my first job ever was for AXA, one of the largest insurance providers in the world where I was a financial adviser. I am am also a Chartered Financial Analyst with a great performance in all levels of the <abbr title="Chartered Financial Analyst">CFA</abbr> and have very decent returns managing family and friend funds.

Transitioning from this laboratory job into IB or management consulting is extremely important to me as I am more into the business and financial elements of healthcare, rather than the clinical elements. Would you guys think my background is good enough? Is there anything I can do to further my chances? I have 4 years of work experience overall.
