Whether to give you a national title is related to the popularity and influence of your company. If your company is well-known in the region or even the whole country, then the title given to you by this company is universal in the region or the whole country. For example, Shenhua Group rated you as a coal mine geological engineer, so all coal mining enterprises in the country recognized it; Like Guizhou Panjiang Clean Coal Co., Ltd., where I am now, this company is only influential and well-known in Guizhou's coal industry, so the evaluation title is only recognized by Guizhou's coal industry, and other provinces may not recognize it. As for the process of evaluating professional titles, for example, our mine evaluation engineer is like this: after graduating from the mine for five years, he didn't make any big mistakes during these five years, and then he passed the computer grade examination and published professional papers in newspapers and magazines in the industry, so he can evaluate engineers.
