Jein, as we say in my part of the world. Working on IT projects in German-speaking countries I’ve quickly found that English is often the lingua franca of a team made up of both German native speakers and random other Europeans. Euro English is not the same as British English: you get a crazy mix of both British and US idioms not to mention an influence from the Indian English dialects when team members have family roots on the subcontinent. British English is one of the dialects spoken and understood in Europe but not the only one and probably not even the most widespread.
