Junior Year Big 4 Advisory Internship to MBB or IB Full-time
I am a junior at an A level school studying health policy, 3.6 cum/3.9 major GPA, and am interning at a Big 4 in advisory this summer. I want to work towards MBB or IB at a bulge bracket firm after graduation. I didn't have any luck with MBB or IB in the internship process.
What do I need to be working on regarding networking etc to pursue a more prestigious full-time position?
How bad is it to accept the full-time offer from the internship while continuing the job search at other firms?
