NCR Corporation interview questions

They arrived at campus for a recruiting event, and I got the opportunity to interview at their HQ by going to this event. The on sight interview consisted of two 45-minute interviews with hiring managers and then a brief tour of the building. The interview questions were technical (relating to the language of your choice) but also high level questions about important CS topics. They also ask algorithm based coding questions where you can use either psuedo-code or a language of your choice.

I got the onsite opportunity from a university career fair, then they scheduled me an onsite interview at NCR HQ 2 weeks later. Interviewees are divided into small groups, each group has 6 people. First they brought us in and toured NCR building a bit, then I did two interviews with two hiring managers, each with 45mins. I bascially aced all the questions they asked me, then it took them 2 weeks to let me know the rejection. Reason is 'the application pool is deep'. Its all about luck, even i am fully prepared, even the 2 hrs are very happy and satisfied with my answers.
