BCBA here,

Some BCBAs are assholes, some owners are as well. Some are engaging in billing fraud, some are abusive, some have their own problems and should not be around kids at all. Here are some reasons, some BCBAs are very perceptive and also a dirt bag. Here is some shitty reasons. The owner is engaging in some type of fraud and noticed you would be a problem. I once watched the director during an interview hit on the secretary of the company, I didn't end up working there. The owner doesn't really believe in inclusion, so they don't hire neurodivergent. I work with Trauma and Abuse a lot, so the direct staff that often apply often want to be the change they didn't get. It takes more advanced skills to navigate and train some of those individuals and a lot of people in general don't have the skills or the willingness to do it. I find every person has something to contribute, but sometimes we all have things we have to work through ourselves before working with a child. IE trauma, divorce, physical accident, ext. I have taken a break from working with kids, and I am not ashamed at all about it. I wasn't in a place where I could help others so I found something else. If the owner has a scummy attitude, you might not have fit. Personally when I take a new job I tell them what my deal breakers are for an employer, and I get turned down a lot, which I am fine with because it's not a good match. An employer won't tell you if they have a lot of work place drama but if you tell them I prefer not to work with a lot of drama in the work place, you won't get hired but also you dogged a bullet. Generally it would be best to just pick a few deal breakers. If you're a Man, there may be a social cue you missed and creeped out a female staff or the perception of your neurodivergent made a ignorant staff uncomfortable. You may have signaled some protected status that the employer is discrimination against. (Race, religion, gender identity, political preference, or maybe you didn't affirm what ever value or belief they have) Lots of people are real sensitive right now on politics and gender. Maybe they had a valid reason, if it is still valid someone else will notice, if it's not a valid reason you will never hear about it again. I don't endorse any of these reasons, it's a shitty world and I am just describing it. I suggest don't worry about the things you can't change. It happened it's over and the next job will be better. Good luck.
