as far as employment goes, my guess is that the Langone adcom wants to be assured that you have enough of a professional background to add to the class (as a potential contact, and as a class contributor), that you have a good job now, and that your employment will be stable through their 2 – 3 yr MBA program.
I would emphasize the upward trend of your career and try to damage control all the mobility by presenting the circumstances (downturns, etc) as challenges you faced and overcame. You want to come off as resourceful and determined to remain stably employed, not flighty and opportunistic.
What is your employment history over the past 2 - 3 years like? I think this timeframe would have the most impact.
