Workshop with a real-life case

I have the opportunity to attend a BB IB workshop with a real-life case. It says that we have to solve the case in teams and then present your findings. But what can you expect and what can I do to prepare myself? 

I took some finance/accounting courses and did the WSO modelling course, but that was roughly a year ago. My technicals are probably below average since I have only prepped myself for a particular quant role.
