Really really depends on the company. I've heard the saying from Siemens people (which in Germany are regarded more like public officials, less like employees): "Freitag um eins macht jeder seins". Meaning no serious work is to be done after Fr 1300.
That company is on a different level. They have their own high schools and private education. Many executives are 'bred' in-house so they actually never even experience 'real life', but graduate from a Siemens high school and start climbing the corporate ladder straight after.
Yeah German corporations, especially industrial ones, can be really dark and sect-like from the perspective of an outsider. Education, intership, job, housing, insurances, life partner, retirement - everything. An entire life lived for a brand, brand owning a city and owned by a city. How far would one go to defend it as a part of one's identity?
