Hello, I also got a lot of PROE certificates when I was at school, which were issued by the National Engineering Association and the Labor Bureau of the local education bureau. But just because you pass those certificates doesn't mean you can really operate it. After graduation, the employer will not look at your other certificates except your diploma. We do mechanical work. During the interview, in addition to asking your professional knowledge, we will let you operate the computer directly. We won't ask if you have any identification. That certificate is very empty.
