I play a lot of competitive games and it is hard to give criticism in a positive way that doesn't make people freak out nowadays.

Here are some of my thoughts. If the person doesn't know enough about something tell them something like: I really appreciate your enthusiasm and interest in the job and would love to hire you in the future. Right now though, we have more candidates with more experience in x, y, z. Here are some resources to help you with those areas and I would love to talk to you again once you get more experience in those areas!

If the person isn't the best candidate you could say something like: Thanks for taking the time out to interview and talk to us over here! You are truly a great candidate and would love to hire you in the future once more positions open up. Until then, I recommend you keep building up experience in x, y, z to become the candidate we and everyone else would immediately snatch up!

I believe if you're honest and helpful you'll come off better than a company that never responds or gives a generic response.

If no one knows what they need to do to get a job, how are they going to get better so you'd want to hire them?
