How to show your professional ability in language during the interview of engineering cost specialty?

I think this job only needs you to have good language skills, otherwise you will suffer more when you contact the owner or the construction party. On the surface, it's just writing and calculating, but it's not. If you are a fresh graduate, it is really difficult to apply for this position. You have never studied engineering, and of course you know nothing about your major. Even if you know something after reading the book, you don't know what others ask you. You can talk about some basic things, such as internship, reading drawings, CAD, and getting good grades in professional courses. If you have work experience, you don't need to be taught how to say it. Don't be introverted, unlike the design institute, as long as the painting is feasible. You have to play many roles in your work, from top to bottom, internally and externally. In a word, the problem involving money is not so easy to solve. You should be flexible, not glib. All this takes time to accumulate. Take your time, don't worry.
