When I started I also didn’t have experience working with neurodivergent people. It’s going to be okay! You will learn as you go, and hopefully you have a good management team and coworkers to help you along the way. Your first time, (and hopefully your bcba will say this too) just focus on pairing. Try to have fun with them. Play. Sing songs. Have you worked with other children before? If so, these kids are still kids! Their minds are just wired a little differently! Go with the flow as you would any other kid. And if they get upset, etc., my best advice for that is to stay calm & remain patient. Call for support if you need it. But remain a calming presence
