Experience with freshers interview

Recently I came across two incidents related to interview of fresh college grads. Both are different scenarios in different places.

1. I interviewed a couple of fresh college grads. When it came to choosing one of them, it was pretty awful. I felt guilty of not able to choose all of them. When all of them are of same calibre, it becomes pretty difficult to choose.

2. In another incident, when you have decided prior hand that you are not going to choose a candidate by screening the resume, it doesn't make sense to call and interview the candidate for namesake. If you happen to do so, then it would be better not to ask some BS questions and reject the candidate. It really spoils the reputation of the organization that you represent. The better way to handle such scenario (in my perspective) is to conduct decent interview, ask relevant questions and let the candidate know the result at the end.
