I've definitely seen evidence of this from a few big name tech employers. Revolving job postings that are regularly re-posted with the exact same details, and it appears that they never actually filled any positions. It's possible that they are hiring a lot of the same job description but these are sort of specialized roles with highly specific job requirements. I have a hard time believing that they are constantly hiring people for a very specific job description and continue to have openings for the same. Seems especially unlikely after they recently had big layoffs. More likely ghost jobs. I think that they aren't planning to fill unless a highly qualified candidate comes along that happens to be desperate and willing to accept a low offer. When that happens, I wouldn't be at all surprised if they hire them to replace someone who is earning significantly more. Potential for big cost savings at the expense of intangible accumulated institutional knowledge and team cohesion/morale.
