Standard Chartered Bank Operations Officer interview questions

It was an walkin in Bangalore rmz eco space.The HR told that there would be first round aptitude then those qualify will have face to face interview.We were made to give aptitude test in the Dell centre where I qualified and they told next week you will have face to face.But time passed but no mail came.They just fooled us .Even my friends told me that they got selected and were told to get joining date but nothing came for six months.I think just for the sake of showing numbers for interview they call Candidates but they have their own candidate from some tied up institutes. I would have given negative rating to this company.Caused me lot of anxiety as I waited for months for the interview.
