The role of qualification certificate is only to play an auxiliary role when you are looking for a job or get a promotion and salary increase at work, and to increase your advantage under the same conditions, but it does not mean that you will definitely find a job or be a leader when you get this certificate.

I personally recommend the certificate of the International Information Certification Association, which was jointly issued by Ministry of Human Resources and Social Security. After all, if it is used in China, it is more authoritative with the participation of government departments.

The employment situation is not good now, so it doesn't hurt to learn more when you have time.
