I applied through an employee referral. The process took 1 week. I interviewed at South Western Railway (Wimbledon) in Jun 2022
Interview
Fairly straight forward, talk about yourself and experience, they then provided drawings, test meter etc with components you had to prove you could use a meter correctly etc. Some basic electrical theory questions put forward such as colour of 3 phase system, how a motor works etc.
Interview questions [1]
