I occasionally bump into job postings that are essentially just a job title, with no description of what the job actually entails. Next to it is a link that indicates how an applicant can contact them to get details about the job posting.
I've seen this many times, but it does not seem as common as the "traditional" approach of just displaying the position's requirements and details directly on the website.
What does a company stand to gain (or lose) by taking this alternative approach instead of being more direct? What things should a company consider when deciding between the two approaches?
