Goldman Sachs Strategic Advisory Solutions (SAS) Group

Hey everyone. Been searching for some information about this group for a while and can't seem to find much information about it. Does anyone know what exactly this group does, if this is a front office role, what the lifestyle is like, and how prestigious this group is?? Also, any information on what the exit opportunities are like for analysts in this group?

On the GS website, it has this group broken up into three practices: Market strategy, portfolio strategy, and business practices.

Information about any or all of these groups within GSAM SAS would be greatly appreciated. Thanks!
