NTT DATA Sr. Business Analyst interview questions

Don't waste the time by giving the series of interviews. Interviewers are good but HR's are not doing their jobs and keeps on telling that they are waiting the Client response. No clarity on the process & never responds to call once interview is done. Beware of online job postings, as I think those are fake. Waited for over a month for the offer letter but they still ask me to wait for next day
