What was the biggest challenge you faced in the last job? What was the outcome and how did you resolve the problem? Actually about the job or the account, I don't have any big problem or challenges. The only challenge I have with my job is the time frame, the schedule, when you are in a graveyard shift and then you must do an overtime unpaid. That is the biggest challenge I experienced, but by getting enough sleep and food, I overcome it and I used to it.
