Career goals essay, too specific?

I have a question as to the level of specificity for the short-term goals aspect of the career goals essay.

For a brief intro, I am currently in accounting/operations at a hedge fund. I’d like to move into investment banking post-MBA, with a long-term view of starting a fund based on my investment banking experiences.

For some schools with high finance placement rates, I’ve said something along the lines of “I want to enter investment banking as an associate serving financial services clients” (industry, function).

However, for other schools outside of NY and major finance powerhouses, but nonetheless do place in investment banking, I think they place in local offices for that area’s industry need (e.g. in Texas it’s energy. For UCLA investment banking it tends to be retail, entertainment co’s.) As I understand, investment banks will place people in groups as well depending on need, so at the end of the day it may not be 100% my choice.

So the question is, if I say I want to go into ibanking serving financial services clients (even though the school is located in an area dominated by other industries), am I shutting the door on myself?

Thank you so much!
