We all have some preferences. Someone likes vanilla ice cream, while someone else prefers strawberry one. It is the same with people. Some of us like to work with children, while some of us prefer to work with alcoholics. Some individuals with special motivation even choose groups such as drug addicts or homeless people.
Recruiters try to find out why you are interested in specific field of social work. In a good answer, you should simply state that you feel close to the target group or to the job itself. To give a specific reason, such as personal experience, is a great idea too.
Anyway, it does not matter what group of people you speak about, you should always speak with love and compassion, as it reflects your feelings to these people and the recruiters will notice it.
Sample answers for different fields of social work
I want to work with orphans, as I believe children need role models in life. What more, nearly all addictions are rooted in bad childhood. I believe that I can change a lot in the world working with orphans and that is why I chose this field.
I was homeless myself four years ago, when I got into serious financial problems. It was the most difficult period of my life. I tried it on my own skin, so I know how these people feel, what they think, what they need. That is the reason for my preferences.
The population of old people in our country is growing. I believe there is nothing worse than solitude, especially when one is old. I want to help the old people to find new challenges and purpose in life and I believe I am good in communication with them. That is the reason for my preferences.
I am not a practical person. I would love to go out amongst people and help, but my social skills are not good enough for doing it. However, the inner calling is strong and I want to help the weakest. I believe that my place is in a sphere of social research. I can satisfy my inner calling to help the others working in this field.
As you can see, there is a good answer for every field you choose. Do not be afraid to be emotional, to talk about your past. It can only help you in the interview.
