Is it dark to openly recruit public institutions? How dark is it? How much worse than the civil service exam?

It's not darkness, it's just that you didn't consider it. Because there is also a contract system within the institution. That is, non-staff members, then these people also need to take exams to become full members. So when recruiting, external candidates don't know what the proportion of internal employees is. If five people become full members, 1 a * * * recruit 10, which means that only five people are actually recruited from outside. Generally, those who become regular can be admitted. I don't need to explain this! That's it. It doesn't belong to darkness.
