As somebody who has been rejected a few times (and been on the other side), I completely disagree. All I care about is speed. A boilerplate rejection in 1 day

As somebody who has been rejected a few times (and been on the other side), I completely disagree. All I care about is speed. A boilerplate rejection in 1 day (or even that night) is 10x better than a more specific email. Also the reasons given in the example emails are so vague I think I would be more annoyed. Rejection sucks, there is little an employer can do to lessen the blow other than do it quickly, so as to avoid days of agony while the candidate waits.
