I disagree.

One of my top concerns if I'm interviewing for a company is, "Are these people going to be sufficiently competent to be fun to work with?" If the interview doesn't provide a good enough filter for incompetence, then I am going to not want to interview there.

If my first experience demonstrates that only competent people will get through, then that is going to improve the company in my eyes.

That said, it will slow hiring down. If you want to hire a bunch of people, you can't put a restrictive filter like that up. But if you just need a few, it can work out in your favor.
