Lateralize in a big 4

Hi, I’ve got a offer at a big 4 to work in transfer pricing (I know its not the best) and after a year or two I want to apply to a more strategy focused sector in this company, how hard it is to do that? I’m currently a senior year student with a major in economics and no previous relevant experience (I’am from Argentina and internships here are not that common), take into account that entry level oportunities for management consumting or ib here are basically non existing, most big banks(jpm, gs, bofa, etc..) ask for at least an mba, and mc firms ask for at least 1 year of experience
