Bank of America Merrill Lynch off-cycle internship

Hi,

May I ask if you have any first-hand advices or personal experiences in the off-cycle internship process at Bank of America Merrill Lynch (London)?
I am really interested in Structured Finance and have applied for the off-cycle internship within BofA's Global Markets Structuring division in London for Spring 2013. My current managing director in the Atlanta office has also sent in her reference letter to support my application. Do you think that is enough? Any advice on how I can best present myself for an interview for the position?

Kind Regards
