Would it be possible to require that employers have a job posting (either public or private) attached to their message to job seekers?
I've recently been encountering a lot of recruiters who are contacting me just because of my C++ experience. After taking time out of my schedule to talk with these recruiters, I come to realize that the only skill I have relevant to the position they're filling is C++, or that the full job description is very unappealing to me.
In one case, I went through two interviews with a company, before realizing that I had no experience with the languages/stack they used, which immediately disqualified me. It wastes a lot of time for both the job seeker and employer when situations like this occur.
I'm not sure how others feel about this, but it would be nice to see a detailed description of the job attached to the initial contact from the employer. It would be much better than 'Oh hey, I see you do a lot of servery C++ development! We do a lot of that, too! Let's talk!' and then scheduling time for an interview, where you realize that the company only uses Java.
