I happen to be Greek and have worked with 2 Turkish colleagues without any issues. On top of that, during my many travels across Europe, Turks (along with other Balkan nationalities) are by far the most welcoming people I meet once they learn that I come from Greece and I befriended a few of them.
Do you have any different experiences to share?
If that's your criteria, who can interview Germans without bias?
Though, yes, all the food is Greek and don't let anyone tell you otherwise.
Edit: corrected cypress misspelling. Thanks repliers!
Just because your experience was fairly positive, that does not negate the general trend of such occurrences in hiring decisions among such pairs ( Greek-Turk, Indian-Pakistani, Japanese-Korean, Japanese-Chinese, Russian-Polish, Serb-Bosniak, Serb-Croat French-Algerian and countless other pairs in the Middle East & other parts of the world )
Theres surely some information that can be gleaned from anecdotes & oral histories. But we need data & objective studies to back them up if we are to make any progress on these issues.
if you do the exhaustive listing probably no one can interview/manage anyone.
and this is before taking into account more finer grained ethnic/religious/cultural/social clashing differences.
a) since such a cumbersome effort to weed out highly
probable biases, that go unnoticed or unchecked, would
likely be too prohibitively expensive for employers to
undertake and hence any such lofty expectations should be
done away with or
b) are you denying the possibility that such biases can
exist in huge numbers in hiring & career growth decisions?
But the latter surely is wrong. It's just that no one wants to be the first to open that can of worms. Thats all.
