I attended an interview in informatica through a company called infogain for front end developer react js, a person called kadir took my interview, he was very offensive and arrogant, after asking only one question he told me, I don't know how you have worked in your previous company with such little knowledge, he was not upto date with current technologies and showed no respect to the candidate, after answering all of his questions and without giving me any coding test, he told I have only theoretical knowledge and at the end he gave my resume back and asked me to keep it myself, in between the interview he kept tell me, you know nothing, I have worked for bigger companies than informatica for 3 years and everyone has always told me I was good at what I do.
