I work for a company that makes rocket engines. It makes no sense to teach the folks in HR about all the disciplines that go into the business - mechanical design, combustion devices, materials and properties, electronics, software, etc. It makes way more sense to make sure they know how to do their own job, and for a hiring manager to be able to tell them something like, "Send me all the applicants who have a computer science degree and at least five years of experience." Then I can evaluate which of those applicants is the best fit based on the resume. The form facilitate that.
