The unlicensed CV Doctor
Dear academic job applicants,
There are circumstances in which it's important to be able to specify the software packages which you can operate. Entry-level stats scholars, for example, often do specify whether they work in SAS, SPSS, etc.
Under no circumstances is "Microsoft Word" a skill worth listing on your C.V. Neither is Power Point or Excel.
Unless you're a certified sys admin, under no circumstances is any version of Windows or a Mac operating system a skill worth listing on your C.V.; it means "I know how to turn my computer on."
And-- really, truly-- under no circumstances is your ability to e-mail or to operate a web browser a skill worth listing on your C.V.
These things aren't just weighted at zero. They make you look ridiculous.
Some things end up weighted at zero-- if the OS you list is Unix or Linux, I don't actually care, but it shows enough tech cred that I understand why you want to list it. Similarly for LaTeX; at the end of the day it's your word processing software and I think it's silly to list, but it's not actively embarrassing. But why bother? Someone with higher tech standards than I might well view it as the equivalent of listing Word, and you'll do yourself damage.
