Every job ad requires a degree because there is no cost to it, and because every qualified person usually has a degree. However no job ad says "a degree is sufficient" -- there are usually other requirements, demonstrated success applying concepts to solve actual problems, a stringent interview process including tests and last but not least, a probation period. On top of that, the degree requirement is usually waived for the right candidate. On the other side is government, for example in some cases if you need approval for the job or a visa, a degree is a government requirement.
