!Rant?

Hey, have been having several job interviews, does anyone have any advice on how to approach being interviewed by people from India, have been doing a lot of job interviews for a lot of companies in the US and seems like I'm interviewing for a position at India, it's very difficult to understand them and often they get offended when asked to repeat themselves... I try to be as positive and optimistic as I can but often poor audio on their part and very thick accent makes it difficult... any tips? this happen to more people? am I the only one?

Thanks...
