Should I Do It?

I found a job opening for a "Behavior Interventionist". If I get the job then I'll be working with kids who have autism. It says no experience is required and it says I will be trained for free. I've never taken care of people like this. The most experience I have with taking care of someone is my younger brothers. I have 3 of them. I think I would do just fine like always do. I always make it work...But have any of you ever done this kind of job before? And if so what can you tell me about it? What was it like? I'm thinking of trying it out because I'm kind of unemployed and they said they would pay $16.25hr. Is it a stressful job?
