We want to recruit a doorman at the reception desk. A colleague introduced a man, but I don't like that man very much. I don't want that man to come to our doorman! !

This is a personal problem. If you are a department head, you can decide according to your own preferences! After all, this job is not a technical job of an important department! Maybe you can't decide! If you also work with him. That's unnecessary. Although you don't like each other, you should learn to adapt. After all, this job for him, perhaps the daily consumption of the family depends on it! So it's hard to bring it up. You can try more contact. See if you can adapt! If not, you can choose to transfer. Staggered commuting time to avoid embarrassment! Moreover, like adapting to a period, maybe the job is not suitable for him, and he will naturally leave!
