I attended a pool campus drive conducted by NTT Data. First we had a written test which was conducted by amcat. Then we had three rounds of interview GD, TR and HR. GD was the process in which most of them got eliminated. Then coming to TR it went for about half an hour. Mostly they were looking for basic skills in c. They told us the result and asked me to attend for HR. And people were again eliminated even in this round. Mostly they asked questions on project and personal things like about myself, ambitions etc.
