Epsilon UI Developer interview questions

Technical Round. We all together friends of 5 went to interview with least and max experience of 4 to 8 years. Well with these all 5, the interview went very good and for all 5 they explained the nature of job and we all 5 thought we went through the interview. But the fact was they did selected any person. Just they wasted to time of the candidate. Please do not attend interview in Epsilon.
