At your old Company, you were quite comfortable. Things worked the way they should work, and everyone had the same vocabulary. You had great training and successful management habits, and these were valued and rewarded by your previous Company. Almost all companies try to establish a strong corporate culture. It is one of the keys to sustaining a business over several generations of management.
Some companies have stronger cultures than others, and are seen by the external world accordingly.
One way or the other, that culture impacts you. This value convergence is a terrific thing. Never belittle the importance of common beliefs. That is what makes the world go round, and should be celebrated. Great companies have great values.
