Which is a better choice?

Hi everyone,

I am currently an analyst in a top BB in CEE in the back office (Finance). My goal is to get an IB role in the UK or US, either through a top MBA or lateral.

The BB I'm at has a tiny front office here (less than 10 people) which does structuring, mostly ABS, MBS and CMBS. The BB also has a credit risk department split into industry coverage groups where analysts assign credit ratings, assess counterparty risk, write credit reports etc on a 1 company per week basis.

I could have an opportunity to transfer into one of those departments soon and would like to decide which one would be better cosidering I want to end up in IB.

I think that structuring is really interesting work and since it's front office obviously more prestigious, however, given my desire to end up in IB rather than trading or AM, would credit be a better choice as they work with bankers and their work is closer (albeit not close) to that of the IBers than structuring, meaning the experience would be more relevant for a lateral move? Additionally, which role would have better impact on admission to a top US/UK MBA?
