With over 850 million users in more than 200 countries, LinkedIn is considered the largest professional network in the world. Founded in 2003, the company has developed into a global player in the online cosmos over two decades. Similar to other social networks, you can create your own profile on LinkedIn, like pages and articles, post updates and - above all - network with other people and communicate via private message. Other users can be found via a search field using their name, employer, place of residence, educational institution or similar criteria. On the one hand, this makes it possible to add already existing contacts to your own LinkedIn network. On the other hand, it also makes it easier to find new contacts who have similar interests or work in the same industry, for example.
