> a team leader or any other particular person cannot interview 500 applicants
While, yes, it often takes interview more than one, and often several people, to find a desirable candidate — it's not that high. Given that any candidate will see probably around 4 interviewers, I don't think asking that the manager interview is that big a deal. I have to agree with that part of the article (though I disagree with it on the whole): meeting your manager-to-be is important. (And I don't think one understands this until one has a bad manager.)
In a prior job, we would also omit the manager interview if it was certain the candidate wasn't going to be a pass.
