why the people are looking for the certification

“Some professional certifications require that you study hard and pass a test, others require that you have years of experience in a specific field before you can even apply to be considered. Before you decide that maybe getting a certification is your ticket to a career jump or a promotion, you need to determine whether or not the types of certifications that will get you ahead in your field are the ones that require skills, experience, or just a few classes”
