Why does hr inform candidates for an interview on weekends?

This kind of thing is very common in the IT Internet industry and has nothing to do with being polite or impolite. I also interviewed a candidate last Sunday. Although I was not in the company, I made an appointment to talk in a coffee shop. The candidate not only didn't think it was impolite and affected his weekend off, but expressed his appreciation for our high efficiency. We were very grateful that we were willing to sacrifice our weekend off to talk to him. In reality, many candidates actually hoped to arrange interviews after office hours, so they didn't have to ask for leave from the company. Back to the topic, there are several possibilities for HR to inform candidates for an interview on weekends: 1. The company is really short of people, and HR is under great pressure to work overtime for recruitment; 2, HR is very dedicated, seeing the right candidate to send an invitation at the first time; 3. The company works overtime on weekends, which is a normal working behavior for HR during normal working hours; In addition, say a few words of workplace advice, if you don't like it, don't disturb it. If you really think it's impolite to inform you to apply for a job at the weekend, you don't have to go. That's your right, but don't be too melodramatic. Maybe this company is not suitable for you, and many similar companies are not suitable for you. However, now is the era of mobile Internet, and communication software such as WeChat Nail has blurred the boundary between going to work and leaving work. It's basically not too good to be completely disturbed by work or colleagues and superiors during off hours. What's more, many bosses are still answering emails in the early hours of the morning, and they arrive at the company early in the morning. We ordinary wage earners, with no background, no good father and no desire to work hard, always want to balance work and life. The company should respect you and think of you everywhere, and the salary should be high and the benefits should be good, and it should be humanized. If you leave on time, you can't work overtime. Isn't this a bit too much? I think, since you come out to work, be mature, and don't be prone to princess disease. It seems that the whole world has to take care of you carefully. The real world really doesn't work like this. Well, if you are not careful, tell the truth again.
