Offers from BARCLAYS/ JP MORGAN/ JEFFERIES. I would love to hear everyones opinion.

I am a college junior ready and eager to start my summer at a big firm. I have been interning my entire college career and am lucky enough to have a few offers on the table. Mind you, I do NOT go to a target school. My offers from Barclays and JP are for Financial Analyst in the finance division. Jefferies is a operational rotational program. The decision I make and my impression on the firm I choose this summer is absolutely vitle. I hope to receive a full time offer from the firm I will choose. I would like to receive my MBA from a target school. I would eventually like to go into investment banking/private equity/hedge fund (dont we all.) I appreciate any advice from people and experts in the industry.

Thank you
