After taking all rounds and discussing salary and finalizing everything the Hr person told me that they you have cleared all rounds ,we will send you salary break up details in 15 mins and offer letter within a week .After that they din't get back to me for next two days.When I contacted them again they said you haven't cleared client round.This was very unprofessional of them.Why they have conducted other rounds when I din't clear most important client round.How they have have promised about offer and declining it at the end.Very very bad experience.Unethical behavior by the most renowned Indian IT company.
