Network Rail Graduate Civil Engineer interview questions

I applied online CV & cover letter. After completing the situation judgment test and the game playing tests (available only in smart devices) I had an invitation to complete the online interview. 5 questions in ones, 1:30 to read the question and up to 2:30 to answer the question.

After passing the first few stages of the hiring process, Network Rail sent me an e-mail for a video interview. So, I signed up to a portal, set my camera and watched the questions. After each question I had around 30 seconds to think and take notes. I had to talk for about 2-3 minutes for each question.
