Wipro Java Developer interview questions

They called @9:00am...400 people came ...only for Java ...@12:30 they took test..very easy test...only 2 panel for f2f..@3:30 called for 1st round... Again waited for 1 hr inside the blocked room....4:30 to 4:50 f2f..very easy question on core Java only...actually interviewer was not prepared well to take interview... Finally @5:00pm they told call you on Monday for HR...worst experience... Entire day wasted without any outcome.

Not that bad. 3 rounds totally. 1st round - written test, 2nd round - technical, 3rd round(telephonic) - technical and current project related stuff. Technical round had questions on collections, concurrency, core java.
