Why is it so difficult to recruit power engineering cost and budget now?

? I don't know where you are from, but I don't think it is difficult to recruit and install here. I am a fresh graduate. They will ask me some professional knowledge, and then let me use drawings to calculate the quantity, so basically an interview will do. They will basically be willing to train new people (installation and decoration can be completed in one year). Of course, they should have enough theoretical knowledge, besides budgeting, they should also know some contract management, bidding and so on. It is impossible for a company to recruit people unilaterally at present. Many companies, whether small or large, want to make the company feel that you are a potential person.
