I was told by the recruiter that if I have not experienced any of the situations she will ask me about I can just answer "I have never faced such a situation". Well personally I think it is better if you have doubts. And of course you have to be careful with the questions like "did you ever have to go agaisnt your boss?" It is very tricky, if you answer "yes" you have to have a really serious reason for that. But then again you should try and answer as many questions as you can to show them that you have a lot of experience.
I also noticed that some of the questions are similar to those in the personality test we had to do before the FI. So you have to be careful again and at least give them more or less the same answers.
Just think before you say anything, you dont have to be 100% honest and if you have experience in customer service then it will not be a problem for you to answer all the questions. Prepare some rady answers in advance and try to look at them with the eyes of the recruiters.
Good luck!
