I made it over time based on observations with my coworkers and my personal work experience (I'm currently a tech lead at PayPal, formerly L4 at Google). What I want to do is to teach people to become good engineers, getting a job should be a side effect of that.
I think mainstream bootcamps value getting a job more than actually becoming a good engineer, which is something I disagree with. This also motivates me to show up at the library every day.
