Honestly - I feel like I don't have enough time with work to be able to "prove" myself enough to get hired. (and also when I study by myself, I get about 0 feedback from others, so I feel like I'm learning terrible practices). I guess two specific questions: 1 - how can I "prove" myself? and 2 - what kind of places actually take junior programmers?
