Social workers meet with all kinds of clients. These clients do often struggle in their life, facing problems, and finding fault with everything around them (that is the reason why they need your help at first).
Being overwhelmed with their own problems, they can be aggressive, angry, sad, irate, or whatever else comes to your mind. Some clients are nice, but many are not. As a social worker you need to deal with that, and recruiters want to know if you have such an experience from the past.
Argument will never solve anything
You can not solve the problem arguing with the client. You probably knew this already… On the contrary, as a good social worker you should stay calm and relaxed, you should keep your focus and goal on your mind, and you should not let their behavior to distract you in work. Remember, your goal is to build bridges, not fences.
I try to avoid conflicts with clients, preparing for each meeting in advance. I try to be friendly and listen more than I talk. However, once I was doing a sensitive questionnaires with divorced women. They got angry at some point. What I did was that I stayed calm and told them that they can refuse to answer any question, and I stressed once again that the questionnaire was anonymous. I also apologized for any inappropriate questions. It helped, and we finished the work without further problems.
I had to deal with angry children regularly, in my previous job at school. I never argued with them, never punished them directly. I just talked to them, listened, paid attention to their needs, and I did what I could to change their point of view. Most of the time, I succeeded to solve the problem.
Describe the situation and offer a simple solution. That’s the best way how to answer this interview question.
