1. Training before security check is really necessary. Because the Civil Aviation Administration now stipulates that security personnel must be certified to work, you must go through specific training before you can work, and then get a certificate.

2. For this job. I don't know what you outsiders think of the work at the airport. It seems that many people think it is good to work in the airport, but in fact they all know that they have to bear great pressure every day and must be able to accept shifts. In many places, there are three shifts of security checks. As for whether the work is hard or not, it depends on what airport you are at. There is a great turnover of security personnel at big airports, because many people can't bear such great work intensity. If it is a small airport, it will be free all day. After all, this is about air defense safety. If you go for salary or something, you will be disappointed. If you yearn for that sense of mission, you will be sincerely proud every time you find contraband.

I wonder if the intermediary company is cheating. What I know is that many airports often need to recruit a large number of people because of the large flow of security personnel. So as an intermediary company, it is not particularly difficult to arrange for some people to enter. But I want to remind you that the safety certificate is very difficult to test. If you don't get the safety certificate, you will never be able to work. Of course, if your organization has a way to get you through the exam, that's another matter.

That's about it. I hope I can help you ~
