The boring truth about why groups don't get invited to interviews

Sorry but there is no logic in this article. If the top 50-60 "stellar" applications will put the other 250 down, this 250 applications are missing something compared to the top 50-60 or they are not very strong in some point, so you can at least reply with an hint, like: The idea could work but you did too little things in the past compared to the best applicants, or for example, the way the application expose the idea give us the feeling you are not addressing the problem in a way we like.

In brief once you are able to see a difference between the stellar and the non-stellar ones you know why the rest is non-stellar and an hint can be a nice feedback for a people that spent some time writing the application.
