This use to be the most embarrassing thing that could happen. A team member asks you why you did something a certain way during a PR and you can't provide an answer. This seems to be becoming the norm now.

It also used to be an indicator that potentially someone was outsourcing their work overseas.

Edit: I had an instance once where about once a month another developer would ask me about workplace setup, mentioned it to someone and was told maybe they were the English speaker of the group. Upon further investigation, that seemed to be the case.
