I'm from the consulting arm of one of the big 4.

Broadly speaking there are three divisions:

1) Management consulting - these guys are supposed to do strategy work, but most of the glam strategy work goes to MBB so the bread and butter is project management work.

2) Tech consulting (I'm in this one) - we do stuff like SAP/dashboard/database implementation etc, again the high-level IT strategy work goes to MBB.

3) HR consulting - they do stuff like human resource role transformation etc.

Anything in particular u wanna know?

haha shhhhh
