Polite rejection from adviser I am a latinamerican student and I am not sure about the responses from potential PhD adviser email responses, I had a very nice interview with one of them who told me that he enjoyed our conversation ( our interview) two days later he wrote me an email in which he said that " I enjoyed our conversation a lot" and that he decided on aother candidate. He also said " be assure that you did an excellent job I just simply had to make a decision"

Is this genuine ? or a polite way to reject me?  I would prefer the truth from a PhD adviser in order to improve other interviews!

In my Country too much politness is not used

Thanks in advance
"I enjoyed our conversation a lot" is a standard phrase and doesn't mean very much. The added "...excellent job..." probably means just that, unfortunately sometimes you get more than one good candidate and he's acknowledging that fact.
