hi;
just saw this, maybe I do not know today's market, most time I will apply both of them, there must be a process to see if you are qualified to that position, right?They shall not deny you because you apply both ..(if you are in USA) Even in other area, I do not think you can not-----they are looking for the best person qualified.
You may need develop a statement---you can contribute to their company either way, it is their choice to put you in what is the best...
