We all experience stress, so it's important not to answer this question stating you don't experience work stress at all. The interviewer wants to see that you can thrive and continue to motivate yourself through challenging days or situations. Discuss where you draw your strength and energy. If possible, mention a time when you came out on top of a profoundly difficult situation. Talk about what you learned through the situation.

"To keep morale high, even during the toughest moments, I never forget to laugh. A person can find the lightheartedness in any situation so, that is where I tend to go. I take my job seriously; however, I do not take myself too seriously. I remain open to learning opportunities and am unafraid to ask for help when I feel that I am drowning in work and responsibilities."
