The main purpose of this story was to emphasize the rather forgotten yet important SQL compared to Python when it comes to employability.
Besides, I didn't state that programming is the easiest skill and to quote myself:
" hiring managers test candidates' SQL proficiency before getting down to the nitty-gritty of data science such as machine learning and deep learning."
This means that SQL is a box to tick and not the whole substance of the interview process.
I guess you missed that part of the story.
