One of the things that is extremely frustrating with job postings is that they are seemingly written for someone who descended from the womb fully trained and equipped for everything they could possibly encounter in workplace (see this recent Harvard Business Review post for more). The candidate will have several experiences doing this one thing as well as several other years doing this other thing (which may not be at all related to the first thing).
The job seeker can rapidly self-omit themselves as possible candidates based on the criteria listed on the job description. These postings also exclude recent graduates and those relatively new to the workforce.
A white paper from the Manpower Group describes a way forward by using Success Mapping by creating a Job Success Profile. You can find the white paper here. It’s worth noting that there are other interesting white papers in the Manpower Research Center.
