What does CSG do?

CSG specializes in garbage. Want to go? If you are not afraid of being tired, go! Tired, very tired, for example, an information technology department is now recruiting a "universal oil" engineer in its own army. I saw that the office computer is actually a junk Dell assembled computer, and 98% of the interview questions for recruitment have nothing to do with the actual work. The so-called recruitment is actually advertising, and there are no ghosts in the factory. .........
