Despite the fact that the resume is designed to give the manager the most accurate idea of you, some things are still better not to specify. 1. “Small” skills, that is, those that are implied in themselves and are developed as if in between cases. These skills are SQL, XML, HTML, etc. For example, if you go to a back-end developer’s job, you better specify MySQL or Oracle than just SQL if you have experience using relational databases, then you probably know SQL and there is no need to specify it separately. Skills of a small order are often entered by people who are not particularly capable of anything, and therefore strive to write more, in the hope that at least something will “hook” the manager.
