COWI was slow to reach out to me. They got back to me many months after my application. However, after the interview, I received an offer within a week.
There's usually only one interview, conducted joinly by the team lead for bridge engineering.
Interview questions [1]
Question 1
No technical questions asked.
Make sure you know why you want to work in civil/structural engineering and are able to answer questions like why civil engineering, why bridges. It always helps if you have done any project/research related to civil engineering. Doesn't have to be much, could be a uni project etc. Also, study some projects that COWI has worked on.
You get a lot of time to ask questions so be sure to ask some good questions.
