Pretty sure I found a bunch of fake jobs in my previous research (H2 2023). Best exemple was an SRE job where I'm a 95% match on the (long and specialized) job description, the 5% being some xp in HPC but they have a dedicated team and a separate job offer for HPC specialist, so that sounds fine.

They tell me I "don't have enough experience with debian" and offer me to apply for the HPC job. I go and list them all the experience I have with every bullet point of the job offer, and mention that I've been using debian for 20 years and ask what specific skillset they are looking for. No answer except "all we can do is start the process for the HPC job".

I ended up finding something else where I'm not particularly interested, have no prior experience, but I'm paid way more than my previous job and they seem to love my work despite it being very slow and frustrating. So I'm just going to stick to that, and give up on the idea of finding "the dream job". More recently I found an offer where they told me they have a "multiple month hiring process" and I stopped answering to emails, pretty sure it's fake as well.
