With regard to lone working, I was reading on here only the other day about people who have passed using going fishing as an example, in their spare time. Think I have read also about people going long distance cycling, which I used to do myself. Cycling is good because you have the concentration aspect, especially when there is a risk of fatigue, planning rest stops, etc.
Not actually sure how the fishing example works, I imagine that whilst you are waiting for a fish to tug your line, you may sit down and read a newspaper which would be classed as alternative distraction. I think in my CBI, I spoke about working alone as a security guard but I do not think I passed with that. I explained how I would be watching the CCTV and walking to the window to watch camera blind-spots every so often, if only to keep awake during the night. I imagine that my assessor probably thought I was watching Total Recall for the umpteenth time.
When did you take your MMI
@Anthony R ? I think the 'high standard' question used to be phrased as, "When did you solve a difficult problem?" Maybe this begs the question about the standards to which you were working when you were trying to overcome the problem.
The 'working alone' question used to be in the old CBI, the predecessor to the MMI. I have never taken the MMI since but I am thinking that working alone would be covered under the question about when you have done a role similar to train driver. Maybe if you have described a role where you were working alone, the interviewer might not need to ask the question.
