alt Hacker NewsA stereotypical Asian interviewing a stereotypical German might find the German rude in some interactions. While another German interviewer would find it being frank.
Interviews based on personal feelings have hidden biases not even the interviewer is aware of.
Here's another question - stereotypical Japanese interviewer, interviewing, back-to-back, a stereotypical Indian and a stereotypical German for the role. Both are capable and equally technically proficient. How do you choose, other than looking at the team you're hiring for, and thinking how the person would fit in?
