"I'm trying to get my first corporate job as a software engineer. I have autism, and this makes me a potential victim of unconscious bias. Therefore, my one non-negotiable is that the company has to have some sort of program or initiative to create an equitable, "neurodiverse" workplace - for example, maybe all employees go through neurodivergency training."

"for example, maybe all employees go through neurodivergency training."

I don't think any company is going to do this for a junior software engineer. Instead the OP needs to think in terms of remote work, limited interaction with others, understanding boss who doesn't want a lot of social chitchat...

We (former startup) hired a deaf intern. Whole company went through training.
