Since SO Careers is supposed to be a new job search site that works better for IT people than anything else out there, I just came up with an idea for a new feature that I would find very helpful that nobody else has. (It might have been suggested before, I don't claim that it's a unique idea. Just that no site is doing it, that I know of.)
I have variations of my CV posted on several job sites, and as some people recommend, I customize it on an almost constant basis. (My SO CV isn't customized as often, since the employers seem free to use language like "ninja" and "rockstar", I wrote my CV to reflect who I am and what I've accomplished and what I want to accomplish in the future, rather than just the uber-formal language used in most resumes.) And I've been job searching for a whole year now, only had 6 phone interviews and only two face to face interviews.
It sure would be nice if I could get some sort of feedback on my CV from the employers. It would of course have to be anonymized. But it would be nice to know if my language is too flippant, too vague, or simply missing some skill. It could even be aggregated and still be valuable. Having one CV that represents me isn't working, and having resumes customized for every job application isn't working either. Some honest feedback would be wonderful.
We could do the same for the job postings. I would comment on job postings that ask for ninjas and rock stars, for example. (Do you really want egotistical people on your team?) I'm also intimidated by those kinds of postings so I don't apply for them, as well as the ones that ask for "expert level knowledge of ..." I've worked with OpenVMS for over 20 years and I don't consider myself an expert even in that. There is always more to learn!
