Why are there some demands for recruiting security personnel like this?

This is a job responsibility, and it is no problem for the recruitment enterprise to fill it out according to its own job requirements.

1. Security personnel need to maintain order and represent the facade of the company, so there is a height requirement.

2. No tattoos. Tattoos, in the eyes of most people, represent some kind of insecurity and violence, so they are not accepted. Not only security personnel, but also many industries and institutions clearly do not accept it.

You can't dye your hair. Similar to point 2, it represents the image of the company, and it is not good to exaggerate hair dyeing.

4. No criminal record, the position is to maintain order and ensure safety, and basically similar positions require proof of criminal record.
