The main thing I want from job descriptions is a salary range. The fact that companies don't post salaries is a strong counter-point to how companies complain about how hard it is to hire software engineers.
I think the post makes some good points. Fluff and buzzword skill lists are useful for entry-level positions, so that a potential candidate who wants to get into a new career and knows little about it has at least some idea of what to look up. But for higher-level positions, the things that candidates want to know about the company and the things that the company wants to know about the candidate, are a bit different, and they both know more about the industry/career path. So fluff and buzzword skill lists are as ineffective in a job description as in a resume.
The tax department here in Norway pays between 80k-130k annually for senior software developers. While earlier this year I got a 55k offer from a private company. I so wanted to show them the job listing from the tax department, but I just said thanks for the interview, but no thanks.
Taking in account of all three, the salary ranges can be too broad. Yeah, Buffer and StackExchange are doing good but then again, quite a lot of times they have been said to be giving low salaries which also is compensated by the fact that they are super-remote-friendly.
I can't imagine if it'd work for every organisation though.
