Value of an IB Internship for Corporate Development

Hi All,

I want to gather opinions on the value of an internship at a boutique investment bank, specifically on whether it will help me transition into corporate development. My background is in consulting and I will be returning back to my previous employer (sponsored) after business school (currently an MBA student). I am interested in moving to corporate development long-term but have been recently told that most groups are composed of ex-bankers. Would an internship in banking look good for my resume when I attempt to switch in the future? Or will most employers just ignore it since it is only an internship and not a full-time position? I will be involved in financial modeling for a few live deals so the internship will allow me to attain deal experience (I have none before). Thank you in advance.

This is a repeat post as my initial post in the IB forum hasn't really garnered any responses.
