Is it true that those online supervision companies recruit supervision engineers?

Generally speaking, it is true, because the mobility of the construction industry is relatively large, and the recruitment of supervision enterprises is normal. If this supervision enterprise intends to develop, it is necessary to consider the personnel reserve of good supervision engineers, so it is generally the case. But you don't need to pay all kinds of fees when recruiting. If you are allowed to try it out, you should be given a certain subsidy.
