They took 2 rounds of interview first was hr interview and next managerial interview everything was good after that they told me ceo was busy so next round would be conducted tommorow next day when i called they told me last round will be conducted on Saturday and when i called on Saturday they asked me whether i had completed the assignment which was never given to me i told them you confirm with interviewer about the assignment an he told the hr that he had given me a assignment but he didn't gave me any i told the hr to give the phone to interviewer to clear the doubt but he was not ready to take the call because he knew no assignment was given just fooling people in name of interview process if u don't want to hire stop wasting time of candidates by giving excuses.
