You will need to see a lawyer to discuss the details. Merely labeling conduct as "harassing," "intimidating" or "bullying" does not mean conduct rises to the level of a legal claim. There is no general legal right or entitlement to a boss who is nice rather than rude or mean.
I agree that you need to speak to an attorney about whether the bullying is actionable.
But it sounds as if there is a cultural issue. It may be a good idea to use your current job as a platform from which to find a new one.
If you found this Answer to be helpful, please mark it as such. Remember, however, free advice is worth every penny you paid for it. This is only generalized commentary on your question. It is not to be taken as legal advice. I am a lawyer – but not your lawyer! Even "in person" interviews leave attorneys with plenty of questions – the Internet makes it crazy!
