I'm not being funny mate, but really you need to know which company your applying to as a complete basic starting point !
I'd hazard a guess it's FGW at Redhill you've applied for, as they've been recruiting lately.
There will be people who have researched the hell out of the role, company and location believe me. At this point there are still 100s of applicants, you really need to red hot with your knowledge and competence questions.
No one on here who values their own future career will openly say this is what they ask you.
Think about the role, the key responsibilities and then think about what type of positive indicators they will be looking for.
Good Luck
