Securities Services Analyst in BB - London vs Corporate Finance Analyst in Big4 - Luxembourg

Hi guys,

First post to ask for your advices. I am about to graduate in central Europe and got two job offers. -A full time analyst program in London at Citi within Securities Services. This is a "front office position" even though we know this is to sell back/middle office services. -An analyst position at Deloitte Luxembourg in corporate finance.

I am really hesitating... On the one hand, I am very attracted by an first experience in London in a BB, on the other hand I know this is more middle/back office related job and I am afraid to stick in this kind of positions in the future. But isn't it better to have an experience in a bank in London than a Big4 in Luxembourg even in M&A?

What are your opinions?

Thanks in advance!!
