"We'll Keep Your Resume On File...
…for consideration for future positions." Well that makes me feel better! A rejection tempered with non-committal possibilities! I'm sure that I will definitely hear from you again, I shouldn't even bother applying anywhere else because you maybe might in some nondescript future time possibly look at my resume for another job that may open up at some point that no one can determine with your company.
I know what you really mean to say. The server of your third-party software client will automatically save my resume to file. Where at some future date (not the same fabled future where my resume will be reviewed again, the actual future) one of their underpaid database managers will have to go through and delete it.
You really should just say: "Don't call us, we won't call you."
