Most of the case you should avoid expressing the conflict situation of your previous job. You can answer this question like: I don’t believe in disputes or conflicts. Generally, I prefer to mind my own business and do my work properly without a chance of complaint. Conflicts are not a bit beneficial for the company as well as for the employees, so it is always better to avoid them. However, unfortunately, if I stuck in any this type of situation, I will use my head calmly and patiently and solve that problem with a healthy conversation.
