I've seen many cases of people buying fake diplomas in my country. This doesn't make any sense to me. What's the point of buying a fake diploma/fake certificate, when don't have skills and your future employer is going to find out, that you are incompetent?
Because the job vacancy require a specific degree/certificate, even the employer find them incompetent, they can making excuse by saying if they forgot with the subject/skill taught in their universities/courses.
Moreover subject/skill taught in university/courses most of time already outdated, so even they have the skill, they need to learn from zero.
If someone who have a real degree need to learn from zero, what's the difference with random people without a degree and willing to learn?
