if they put your nationality as the preferred candidate, would you be reacting the same?

HR departments run their ads based on the level of their needs. There are many factors considered and does not in any way mean to inflict harm to anybody.

You began your post with a curse, this is ONE THING that is truly not Filipino and that is the reason maybe for the preference.

Shame on you for blaming others and showed your true nature of being a racist.
