I made a job call through my relatives. I don't know the rest. How should I ask politely?

Since it is a recruitment, it is better to come straight to the point. You can ask, "Hello, is your company currently recruiting new people?" I would like to ask, what positions are your company still recruiting? I also want to know whether I meet the recruitment requirements in your ",because it is a recruitment phone, so I must be brief and to the point. After a few courtesies, get down to business. If you are too polite, it will make people feel disgusted.
