It is said that it is a recruitment network to promote marketing, and it is also said that it is a trader, and there is no basic salary. Should I go?

You can't go to this one. You said you had been a programmer for four or five years. I think you should continue to be a programmer. Don't change jobs to improve communication. Really, you can improve through other things, make more friends, travel more and broaden your horizons. I think this is feasible. You should continue to be a programmer. All walks of life have their own advantages. Don't increase your spare time because of small losses.
