You kid about it but I was curious enough to search for Civil Engineering interview questions:
https://targetjobs.co.uk/career-sectors/civil-and-structural...
Some examples:
Being asked the following questions in an interview: ‘You are going to build the bridge that you were given as a case study earlier this morning. What are the ground investigation steps that you need to undertake? What sort of tests will you do?’
At the end of an interview being given some beam sketches and being asked to draw the shear force diagram and bending moment diagram.
Being asked to draw a strip foundation and build up to how you'd construct a suspended slab.
Being asked what factors you would need to take into account if asking to site a railway station.
