What challenges you have faced in testing so far?

This one is a tricky question; interviewer wants to know firsthand information from you about your weakness in handling difficult or crisis situation. Answering this question like what is your weakness – you need to keep yourself specific and not to lament problem or difficulties or show any kind of annoyance or hatred for particular stack holder or reporting manager, colleague or developer or some process. You can explain situation however, but should end your statement expla ining how you were successful in controlling the situation.
