Is it optimistic or depressing when you’re at the point when you’re elated just to hear an echo of a response back from the other end of the void?
Dear Tim,
Thank you for applying for the xxx summer internship. We chose another candidate whose qualifications were a bit more in line with what we were looking for this year, but you should know that we received dozens of applications, and yours was one of the strongest.
We really appreciate your interest, and I hope you continue to read xxx. Best of luck with everything, and have a great summer.
Yours,
Editor Guy

that is one of the nicest rejections I’ve ever read! the void is soooo terribly depressing.
Not much money in summer internships.
(I’m also applying to them.)
