The amount I learned in the compressed time frame was everything I needed to do the job as a jr. front end dev.
Unfortunately, the coding interview is a whole other beast and HR spends the last week of the session focusing on the job search and interview skills. They do offer job search support for up to six months post graduation. The job market was competitive in 2018 and I also believe I, a 40-something white man, was demographically challenged in the marketplace. I was also looking for work in the Bay Area, the most competitive location possible - where others of my cohort could be more flexible with regards to location. That, plus my interview skills are weak and I was counting on getting lucky or a fair interview.
Now that everything is remote, I think you can widen your search net to companies outside of SF, leading to hopefully better odds.
I would still highly recommend Hack Reactor but expect your job search may take up to six months (in my case eight!)
