The interview was a fairly general interview, but I was asked a few technical questions, which I was unable to answer as a university student. To be honest, I took a portfolio of university work, and they asked me questions about it, but I wasn't able to answer them correctly. Also got given a frame or beam with loads and had to draw a bending moment and shear force diagram, which I believe I drew incorrectly and was visibly struggling with. So yeah, definitely be well prepared with your shear force and bending diagrams, and if you take any portfolio or project examples, be sure to understand them properly.
