This one is hard as I have a gut feeling that sometimes it does happen as I have an Anglo name but am Asian-American. However, if it does happen, it may also be a place or team I wouldn't want to work for.

It's hard to explain but the 'bro'-ism can be deeper than you may think. Let alone a cultural fit a manager may be trying to achieve - as "cult of personality" will also tend to pull out all the stops to "prove" themselves..

But without feedback from the interview loops, we just don't really know.
