Hi js,
In the CBI I was asked to (If you can think of 2 examples for each question and put the one you feel is strongest but be prepared in case they ask you to give another):
Describe a time when I have had to follow Rules and Procedures- giving examples of what they were, why I had to follow them, how I felt about following them, what would happen if I didn't follow them
DESCRIBE A SITUATION OF WHEN YOU HAVE DEALT WITH AN UNEXPECTED SITUATION OR AN EMERGENCY? Giving examples of what it was, why you did what you did, how you felt, what would happened in the end?
Have you ever had to dealt with a big problem? How did you solve it? How did you feel about this?
The Managers Interview will involve much of same and additionally:
What do you know about London Overground?
Describe 3 Key Things that a Conductor does?
Describe Customer Service/Satisfaction in 3 words?
Describe a time when you have disagreed with a set rule passed down by Management?
Describe a time when you worked in a team? What did you do?
Describe a situation where you gave good Customer Service?
How would you get into work for 4am?
Have you done shift work before?
Good luck and let me know how you got on
PS I got through!
