I did well! - as i'm now driving for Northern
The questions were very similar. I can't actually recall the specific questions - it was nearly a year ago - but I think if you cherry pick your best answers relating to:
- Keeping Calm under pressure;
- Dealing with an emergency;
- Working alone for long periods of time;
- Solving a problem;
- Following Rules and Regulations
- Prioritising;
- Working as part of a team;
- A time delivering a difficult message.
There were 5, and you get 25 minutes to decide and bullet point or provide a paragraph to assist the interviewer. There are sub-questions too. I know I was definitely asked about working alone for a long period of time: and I was 'probed' shall we say with things like "How did you cope with boredom?" and "How did it affect your concentration". The core competencies above overlap and can be interchangeable - so make sure you have a good handful of examples to mind.
They are flexible - and if your example isn't up to scratch - you get a minute or two to suggest another example!
Best of luck.
