I still remember as a 25yr old programmer in England, attending a job in what was basically a porta-cabin in the countryside around Birmingham. Inside all the walls were covered in 1980s "Hang in there" motivational posters, only they were originals and it was unironic ( it was like a time capsule ). After shocking the boss by agreeing to a cup of water offered by the secretary which caused a massive problem as they had no glasses, the over weight boss sat me down and asked me:
"What percentage of windows is written in C++?" The position was for web development...
I guessed correctly ( it was about 40% ).
I then apparently failed the interview as he suddenly asked me if my girlfriend wanted to interview for the position ( there was no indication she was even in the field of CS ).
The moral of the story is apparently the code ratio of Microsoft products is a big deal to random middle managers in the black country. ( Thats what the region is called because the soot from coal mining would blacken the landscape - yes its what Mordor was based on by Tolkien).
