Second, if you are afraid of being unreliable, you can go to various recruitment websites to search the company's recruitment information, such as Worry-Free Future, ChinaHR.com, Kufang.com, Zhaopin.com and Avenue.com. Generally, the things posted on these platforms are quite reliable, and then you can go to the special construction industry website to have a look. If the company is big enough and good enough, these places should also have recruitment information.
Third, you can go to the national enterprise credit information publicity system to check the company's business license or something.
Fourth, there are a large number of recruiters. There may be a large number of people in the construction industry recruiting general workers, and a small number of people are recruiting engineering cost-makers, budget-makers and draftsmen. You can call for advice according to the position you want to interview. There is no feedback from the company's recruitment or interview on the internet, and they may not have written it. Of course, I don't know what the specific situation is. I suggest consulting first, then positioning, and then preparing for the interview if you decide to go. I wish you a successful interview.
