In ramping up the field organization, Google has sifted through many experienced individuals and selected only those that met a high internal standard. Or so it was supposed to be and some are now showing their real stripes. One VP has talked about how Cloud culture needed to be different than Google culture. Others in various management positions are now trying to implement cultural elements from Microsoft, Oracle, VMware, etc. and are increasingly denouncing Google culture. TK has started to bring in his own people from Oracle, some of which should never have been able to get through the interview process.
As a result, the change is underway. Some who wish to transfer out to other positions are being blocked. Everyone is being required to go through assessments to measure their suitability for their current roles. Compensation is being re-evaluated. An entirely new tier of management, primarily from outside the company, is being brought in to shake things up (including HD from Oracle).
Google culture used to be a differentiator. Now Google Cloud won't be that different from AWS, Microsoft or Oracle.
