Bootcamps/courses for experienced developers?

If you haven't already made a decision, check out Formation.dev (disclosure: I'm a co-founder). It might be a good fit and you should look into it and do your own research. It's not a bootcamp with a structured curriculum, nor is it a job hunt only program. We work with people to fill in whatever gaps they have across the board (technical and behavioral), refer you to top tier jobs, help you interview and negotiate, etc... And we work with you on your schedule all the way until you get your new job. Our last ten placements (at time of writing) were at Plaid, 1Password, GitHub, Microsoft, Google, Meta, Google, Snap, Atlassian. Many of these engineers went to bootcamps in the past. I also don't really know any other programs like this at the time of writing, perhaps having several private mentors who is are senior engineers at top tier companies and paying them directly?
