There are discussions about sitting for an exam or certification and in some cases, having certification is the requirement to get hired to a company. However , there are following arguments:
1) Certification does not proves you are an expert
2) There is no guarantee not having certification meaning you are not an expert
3) During exam, you might get lucky and see all questions you know or be unlucky and see questions you don't know.
4) Industry experience shows having or not having certification doesn't proves anything
Therefore, I believe the certification shouldn't be requirement for an hiring process and instead we need to focus on knowledge and expertise with other means and getting certified should be placed as an option.
