Citi Corporate Banking Groups

Hi Monkeys,

I want to apply to Citi's corporate bank, but aside from the obvious sector coverage that they have, I do not know what the groups within the division actually do. There don't seem to be any resources available online, and searches here have yielded nothing.

Would anyone have any insight? I am specifically curious about:
-Capital Strategy Group
-Transaction Execution Group
-Global Subsidiaries Group
-Global Capital Management
-Communications (that could be sector coverage I guess...)

Hope everyone's holiday season has been fun so far.
