Consultancy Culture vs IBD

Started applying for Strategy Consulting and just wanted to know something.

Now i've worked in IBD for a summer and saw loads of analyst and one associate getting shouted at and humiliated by MD's...

Just wanted to know whether this also occured in Strategy Consultancy? (McKinsey/Deloitte/LEK/Oliver Wyman etc)

Or are Strategy Consultants more "friendlier" down to earth people?
