What questions do interviewers usually ask when recruiting construction workers?

I want to spit out all the questions I asked. Work 1 1 year, interview no less than 10 times. Some interviewers don't understand professional knowledge at all, and all they ask are amateur questions. Briefly talk about a few laymen: how to pour the frame column with a height of 15 meters; How to pour a 2-meter-square 4-meter-high frame column? Where is the construction joint suitable? How much is suitable for arching of 8-meter-span frame beams? What materials are commonly used in basement waterproof construction? What should be paid attention to in mass concrete pouring? What is the unconnected area of frame columns?
