Honestly you could have just saved us all this time by stating you're a hiring manager up front.
I appreciate your optimism regarding the nature of these postings, but I've seen at multiple companies them doing exactly what they describe in the article - fake job postings to improve their appearance to investors, fake job postings to justify H1B positions, etc. Every time I was at a company that got bought by private equity, the former appeared in huge numbers. As soon as we got acquired, in preparation for downsizing, the latter appeared in huge numbers. So you'll forgive me if "managing job hard :(" doesn't land for those of us who are applying for those jobs that don't exist.
