I used to work for SKP before moving to MBB.
I would say SKP culture is one of the weaker points of the firm.
During my time in the firm I never felt the leadership to be much involved into the development of junior members or even promoting a good work environment within the office.
Relationship between colleagues its like any other firm.
I always felt relationship between us and clients was extremely transactional, compared to MBB where I see we are perceived as “advisors” quite often.
At the end of the day SKP is still pretty much a marketing consultancy where you will spend majority of your time doing surveys that have little impact in shaping your client's organization.
At least the hours are a better.
