[1] https://www.jobs.now/blog/unveiling-the-truth-about-h-1b-vis... "The Jobs.Now team has reviewed job postings from dozens of top companies like Meta, Block, Doordash, and Netflix which require unusual application processes like emailing or paper-mailing the application to specialized addresses, or using unbranded separate websites for collecting applications for jobs." + search for occurrence of "Apple" [2] "My understanding is that this is pretty much how everyone does it, no?"
