professional accreditation
If you want to be recognized by the industry, you can take some professional certifications. It should be noted that due to the particularity of the industry, most manufacturers' professional certification has not been liberalized, and non-enterprise employees cannot pass the exam, while a small number of external certification training costs are high.
National certification
National certification should only be available to fresh graduates, but the specific situation needs to refer to the requirements of various certification bodies. If you have H3C certification or cisco certified, you will be more competitive in job hunting. These certifications are particularly important in the mobile communication industry, because now we are in the era of triple play.
Software authentication
If you are interested in software, Android and other fields, you can try to take some relevant certificates. It should be noted that there are many kinds of certifications, so you need to carefully choose the one that suits you to avoid wasting time and money.
