innoPath Software Engineer interview questions

compare with other companies I interviewed and received job offers like Yahoo, VMWare, eBay.. the engineer of innoath who did the phonescreen with me was rude, arrogant, and had a strong indian accent, which made me very hard to understand his questions, for example when he asked me what's Java Comparable interface, which sounds like Compatible interface. I feel like it's a totally waste of time given their discourtesy.
