But.... you're a "lady"!

So I had my first job interview today. First, they gave me an IQ test with a hundred pattern recognition questions... I think I bombed it :S. By the time I got to question 35, my brain was all fuzzy... This was followed by a verbal and math section along the lines of the GRE (I think this part was ok). Then came the personal interview. The HR person interviewing me was probably in his mid-fifties with a beard and pot-belly :). Clearly, he hadn't looked at my resume before because when I walked in, he went, "Lekin aap to lady hain!" ("But you're a lady!"). For the record, my real name is completely feminine. Completely nonplussed here :S
