Personally, I think it's not bad, because I just reported for work half a month ago. Now, their teacher is very serious and responsible. Every time there is a new question or answer, it will be posted in the group in time, so that we can see it first hand. The company is also quite big, and its strength is relatively strong. Not that kind of small company, after all, big companies have strong financial resources and strong teachers. I suggest you visit them more and learn more about their manners.
