Once again my department is putting together a job ad. There's been much discussion over the wording of the ad and exactly how we want to phrase every last detail. Frankly, the minutia of picking one word over another because of subtle differences in implication is rather pointless in today's job market. People aren't worried about the exact phrasing including or excluding them because it doesn't.
One thing I always fight hard for, however, is that we not ask for letters of reference, up front. Why? I mean, maybe an LoR is so good it puts someone on the shortish list! But do the math. Let's say you are advertising a specialized position and you get 100 applications. Three LoRs per application gives you 300 LoRs. If you plan to phone interview 10, there's a really good chance there's nearly 270 LoRs that will never or barely be read.
It does not take much time to send off an LoR, this I know. But it's one more deadline for busy people. In fact, unless the job candidate is a special snowflake, there's a pretty good chance that it's 30-40 more deadlines for busy people. And for what? So the committee can maybe argue a little longer over numbers 10 and 11 on the list? Please.
If you are involved in a job search, do your community a favor. Don't ask for LoRs until the shortish list. Those 30 people will actually feel like they are helping the candidate rather than mailing out fliers for a job-a-thon.
