Cute but useless.
* 99% of jobs advertised online are fake, including HN's Who's Hiring. They are posted just because some manager wanted to fake growth, wanted to pretend fairness for a position that will be given to patronage, forgot to remove an add posted long ago, etc. Like in online dating, online job postings is mostly a scam.
* The "most wanted" skills are somewhere between the "junior skills that are necessary but not sufficient" and "rat race". They are the skills most likely to be replaced by AI or cheaper workers from 3rd world countries.
I've applied for online jobs, I've been through the pain.
There are only 3 ways of applying to online jobs that preserve your emotional health:
* Use an automated tool like loopcv, Sonara, Jobscan, LazyApply, SimplifyJobs, Massive, etc. Yes, they're crappy. But with enough quantity, quality of application becomes irrelevant.
* let recruiters find you, don't search for them
* look for positions in fora dedicated to specific/niche technologies (e.g.: Reddit, Dischord, etc).
