For what it may be worth: I joined in 2003 the part of IBM that was essentially the very-recent acquisition of PWC Consulting. I believe that was ~30k [1] employees ingested (compared to Redhat's <15k). Now, my limited view and perspective is as a bottoms-up techie grunt during this period, but my very personal observations are: 1. Absolutely, PWC got assimilated over time. However: 2. For the first 5 years, culture in my part of BCS was 90+% PWC culture. Perceptible (again, from bottoms-up perspective, I'm sure lots more was brewing in the background) changes started creeping around 2007-2010 mark. 3. Today, 17 years later, I would claim it's a hybrid mix. We are clearly not the same as we were during PWC private-ownership, partnership-structure - no public company can be; but we are still different culturally than rest of the IBM. 4. Perhaps most convincingly, I'd say 70-80% of people I knew in 2003 in my part of IBM, who were originally from PWC, stayed for ~15 years. When many of them moved on ~~2017, it was for a very specific and very different reason. A whole bunch still remain though, including much of the senior management / partner / executive structure (my direct peers and management are all still ex-PWC). Again, FWIW - there will be a myriad experiences and stories in this complex picture, but that's been my experience. 1: https://www-03.ibm.com/press/us/en/pressrelease/491.wss https://www-03.ibm.com/press/us/en/pressrelease/491.wss
