This is the correct answer.

One can come into contact with many of the same "rude" type, but it's generally due to the fact that hiring in any given organization is generally based, at least in part, on "cultural fit". This means the various types of engineers will tend to segregate a bit over time. For instance someone who is a bit more contemplative may not meet the "cultural fit" requirement at a crypto defi shop, but might do well at a national laboratory. (And vice versa). This is why we shouldn't meet a group of, let's say "strong personality types", and assume that all engineers in other places are similar in nature. That's not at all how it works.
