I applied online. The process took 2 months. I interviewed at Network Rail (Milton Keynes, England) in Jan 2018
Interview
Fairly simple. Application, online tests, video interview and then assessment centre. The video interview were all situational based questions with plenty of time to answer. The assessment centre was very relaxed but there were quite a few candidates there.
Interview questions [1]
Question 1
How would you persuade a mechanical engineer that they should invest in a Management accountant instead of investing in ballast?
