I applied online. The process took 3 weeks. I interviewed at Network Rail (Milton Keynes, England) in Sep 2018
Interview
Smooth interview, one short test. It lasted around 1 hour with two people asking questions. There was a second interview once I passed the initial one. There were many questions based on a formulaic workbank. They scribe what you say.
Interview questions [1]
