Job satisfaction will contribute to one's productivity, staving off burn-out syndrome and enhancing one's work/life balance. Everyone will have their own particular triggers that cause them to feel dissatisfaction with a job. Feel free to share with your interviewer any factors that may deflate or discourage you in the workplace. However, where you can try to keep things positive and focus on the positives you look for in an optimal work environment, such as trust, recognition, enhanced team collaboration, and camaraderie. Share how, when those positives are absent, a work environment is less than ideal. Attitude and perspective are everything here.
