Family, friends, acquaintances, employers, etc. can learn more about us online, for example, by creating a profile in a social network. An online profile and other contributions on the Internet can influence the opinion of others both positively and negatively. In your job, you can attract attention through a good self-presentation on the Internet. For example, posts can highlight personal interests from the professional field and previous experience and thus arouse the interest of employers. However, it should be remembered that one can also quickly convey a false or transfigured image of oneself. Therefore a conscious selection of photos, comments, links and the like is important.
