Oh man, I remember having an interview with a hungarian team for a videochat platform (I wasn't fully aware that its related to videochat or pornography until the end of the interview), the technical lead corrected me on what CORS is, and he did it wrongfully. I opened mozilla docs for CORS and proved to him that I was right, he told me that using external sources during interviews is forbidden and rejected me. This was quite a few good years before covid happened and I am so glad I didn't join that shit team.
