Well, just reading the first few paragraphs made me close the article instead of thinking about it.
we took 300 job specs
Thatʼs a very small data set to inspect. If you want reliable data on this topic you need data 10 times of that.
AWS being the first on this list makes me really suspicious. Itʼs a huge topic that only slightly overlaps with Python. Also, after manually scraping a few Python job ads i didnʼt find it mentioned other than “our infrastructure runs on AWS” but that barely means i as a Python den must know how AWS works.
All in all, this whole list made me a bit mad. It definitely doesnʼt cover everything, the title itself is a nice click-bait, and itʼs generally inaccurate. Never look for jobs this way.
