MSCI RFP Support interview questions

When i went for face to face interview, the interviewer asked me questions which i answered to all most of them.. My interview went soo positive and they where impressed too.. Interviewer asked me to wait till the HR comes.. I waited till 1 hour and suddenly they asked me to leave for the day.. When i tried to reach them my call.. They said we will let you know.. It was the worst experience they didn't responded later also... . It seems it was a fake interview.. Or don't take interview if you don't want to hier.. It really breaksdown the confidence When you are assured of getting hiered and you didn't get response... . . Coming this form the firm is really not expected
