I started seeing the trickle of bootcamp grads coming in maybe 7-8 years ago. Many of them were just as good as the CS grads. They have no issue finding new jobs today, some are even at FAANG
Someone who went from bootcamp to coding 6 years ago shouldn't have any issue finding a coding job today, if they're actually good and progressed over those 6 years and have worked a year or 2 as a senior engineer at a good/known company. My guess is they aren't
Companies today want people who can hit the ground running. Less jobs for juniors, less jobs for ramping up within 3-4 months.
