Interviewer clearly prefers candidate from his region, he was being rude , clearly not interested in hiring right candidate for the company, but want to belittle the candidate, if the candidate does not agree with his view point , the interviewer himself did not know difference between url of a page and anchor links in the page . If wants to reject you , the interviewer takes up any random program from internet and straight away say your approach is wrong even before hearing you out . I do feel people from south of India are discriminated here . It's a waste of time interviewing here .
