I don't think so. Not to mention that it is difficult to find a job now, and you can get a certificate. Actually, it's useless. I think it is necessary to take the postgraduate entrance examination and then take a part-time job in my spare time. If you coordinate, you will always get tired of watching it. Of course, if you have the energy, it is understandable to get a certificate. I think the most important thing is work experience.
