I see a couple of points there.
I don't have the precise statistic on the American refusal versus acceptance rate through the interview process. I do not have that available. We could try to get it, but I'm not sure. It would take a little bit of work to get that.
We have looked at interviews. A number of years ago, we did far more interviews than we do now. Frankly, we did not find them to be an overly useful process in the vast majority of cases. We still do interview some applicants, for sure, and in some instances it is extremely useful to have the interview, to have that face-to-face contact and to be able to speak with individuals. But in the vast majority of cases, we don't find that it's necessary or that the results are much different from just doing it on paper.
