I wouldn't volunteer the information, but I have had 3 Interviews where the question came up: "What was a difficult situation that you had to deal with, and how did you go about solving it". There will always be challenges which you will have to overcome, and the ability to deal with them calmly and effectively is a rare skill which companies find invaluable. However, opening any conversation with 'I expect to fail' could go just as much against you as in your favor. Be prepared to talk about your problem solving methodology, your reactions to stressful situations, and your any strengths that you may have in working with others. These are universal concerns for all employees. It is true that failure is inevitable, but the lessons learned from hardship are the ones that stick with you.
