WeWork Community Lead interview questions

I had four interviews for a Community Associate position in Berlin over a period of 3 months. The first interview was 30 minutes via video call, the second an hour-long video call, the third a two hour in-person building visit/interview in German and English, and the fourth another 30 minute call with a more high-ranking employee. At the end of the interview process, it was clear I was overqualified for the job, so I was offered a position as a Community Lead instead. I was offered the position over the phone, without a formal offer yet, and I preliminarily accepted. However, when I mentioned that I was in Germany on a Job Seeker residence permit (something I had mentioned in my interviews), the HR employee offering me the position clearly had a lack of knowledge about what this meant and assumed I did not have the right to work and would need to be sponsored. This is not the case; no matter how many calls and emails I exchanged in an effort to explain that I only needed an offer to convert my existing residence permit to a work permit, and this takes very little time and no extra effort whatsoever on their part, the communication proved to be frustrating, anxiety-inducing, and completely fruitless. I even got a lawyer involved to facilitate the conversation and explain my rights. Despite all of this, the global mobility team continually misinterpreted the law and the process entirely, and the informal offer I received was retracted via email. I was baffled at the incompetence on their side. The lawyer told me after this nightmare that the way everything turned out and the reasons used to retract my offer would constitute grounds for a discrimination lawsuit (as I am an immigrant without an EU passport, but I did have the right to work in Germany through my residence permit), which I didn't go through with, but probably should have for the sake of everyone else in the future. What is ordinarily a very standard hiring process elsewhere turned out to be an awful, disappointing, and discriminatory waste of over 3 months. Inclusion and diversity is unfortunately not put into action. This is not to mention every other massive issue with the company. If you are an immigrant, please be careful with investing your efforts here—the company bungled my very simple case so badly that I can only recommend saving yourself the mistreatment and applying anywhere else.
