B School Essay.. Career Advice?

Hello All,

I am hoping someone can give me some perspective. I am applying to HBS and they specifically ask about career aspirations and they only give you 500 characters.

I am thinking of writing something along the lines of

"As pharmaceutical, biotech, and medical device companies have faced major challenges such as pricing pressures they have looked to operations to maximize profits. Therefore upon graduation I would like to work as a consultant for a top pharmaceutical consulting firm such as xxxxx and focus on operations. Following 4-5 years in consulting, I would like to enter a large pharmaceutical company as a senior manager in their operations department."

However this does not show why I need a MBA. Does anyone have any insight on if this is a problem or if I should completely re think my line of thought.

Its just tough to include why an MBA with 500 characters.

Any help would be greatly appreciated!
