Jifflenow UI Developer interview questions

Got a call from consultancy. 1st round was telephonic. Pretty good. They were looking master in all technologies. Then gave an assignment to complete in a week. The objective of the assignment was not clear. Then got a call for F2F interview. It was like hell for me to search company location. The interviewer was a pretty young guy and the questions were so tough and looking he copied from stakeoverflow.
