Commercial Banking Financial Analyst Interview Case Study

Hey guys,

 I'm looking for some tips as to how I might prepare for a case study interview for a commercial banking analyst position.  My research tells me that this will be part of the interview process.  I feel good about behavioral and technical questions, but I haven't seen any examples of what the case study question might look like.  Most of the other case study threads here are for higher level positions.  I expect mine to be fairly basic for an entry level position, but I have no direct experience so I don't want to blow it.  Any tips are appreciated.
