Calypso Technology interview questions

5 stages of interviews - seems managers do not speak to each other as many questions i had to repeat myself. It took 4 weeks to hear back after chasing TA on Numerous occasions.

They were interviewing for three or more years experienced Java developer but their questions were very easy. They took three rounds of interviews and I answered all of their questions correctly but they did not gave any call or feedback. They are only waisting time. Questions were on OOPs, Collection, multithreading.
