I was told that there will be a phone interview followed by a in-person interview. Cleared the Phone interview and i was asked to wait for in-person interview but some one called again to go over second round of Phone Interview, He was unprofessional and very rude, he asked me how i would map the Json data to html page. I said, I will either have it as a partial view and deliver the html content or i will use Json parse and Jquery to set each element. He asked me about "Knockout.js" but I said I never used it, then he started bragging about "Knockout.js" and thought i am not worthy developer because he used a Java Script library that i never used.
