We use this question mostly when interviewing applicants for jobs in nursing homes, or in other facilities where they would deal with old people, young children, or patients suffering from mental disorders and dementia.
It is a technical question that refers to a difficult situation you can realistically face in your job, and we will ask you several questions of this type in an interview. They will be related to the particular group of people you will work with in the job.
There is always a way
Good social workers are patient. Communication problems should not discourage you. You should say that you’d stay calm and try to find an alternative way of getting your message to the other side.
One good way of doing that is going by an example. If you want your client to do something, but they do not understand, demonstrate the action. Show them what you expect them to do. They may often repeat it.
To use pictures, gestures, and other forms of getting your message over is also something you can mention in your interview answer. However, the most important thing is your attitude. Say that you would stay calm and try all possible means of communication with the client.
