How hard is it to get a junior fullstack job now?

On a scale of 1 to 10? What kind of answer do you expect? Some people get jobs easily, others struggle to get an interview after a year. I don't think all of those experiences can get reduced to a single answer. Like everyone else your results will mostly depend on your skills, experience, professional network, and luck.

I heard it is quite difficult. But it has literally never been easier to make a profit coding your own things

basically impossible for some of us
