2 years ago, while interviewing internally, I asked the team what VC they use. It was Team Foundation's proprietary VC (and not a DVCS). I mentioned to them that even MS recommends Git for Team Foundation's usage.
"Well of course, MS invented Git!"
Wrong on so many levels:
1. Conflating Github with Git.
2. They bought it, not invented/founded it.
3. Most importantly, MS's recommendation to use Git for TF existed long before they bought Github.
Needless to say, I didn't join that team. Unfortunately, misconceptions like these, and a refusal to use Git[1] due to its complexity are quite common at the company - and it is one of the larger SW companies[2] in the country.
[1] I'm OK with any DVCS. Even I prefer Mercurial to Git. But most of the company prefers SVN or TF's version control. In 2015, many teams had to be dragged kicking and screaming by IT from CVS to SVN. In 2015, when Git already dominated the world.
[2] By number of employees with "SW " in their title. Not by revenue, etc.
