Richie Rich Services interview questions

Question regarding technical study and GK question. First it started with introduction, then basic questions regarding engineering concepts were asked. After that HR round was done and finally Quality Sr. Manager took the interview before final selection.

Biased towards my race because I was not Hispanic or could not speak spanish. They started speaking Spanish all around me. As I looked around all I saw was Hispanic people that looked at me like I was not supposed to be there it was a very negative experience for an employer to take a interviewee through.
