Bootcamps for engineers with 2+ years of experience?

Hi, someone tagged me as I'm the co-founder of Formation, which is a program for experienced engineers to help them work on fundamentals and prepare for interviews. So the topics you mentioned, we cover System Design in general, which is high level architecture and API design, and several of our competitors, like Interview Kickstart, also cover this topic. We don't go into specific hands on practice in specific tools because typically experienced engineers will learn that on the job in some way, and the more important things to learn is fundamental abstract thinking around these systems. Most companies have such complex internal frameworks that knowing specific tools is less useful for experienced engineers. I'm not sure if Formation is right for you or not, but I'm fairly sure a bootcamp isn't. Some bootcamps will flash those words around, like Codesmith for example, but the depth is not what you are looking for if you are an experienced engineer. At Formation you'll spend a few weeks learning how to think about large systems with Senior, Staff, and Principal engineers are Reddit, Spotify, Facebook, etc... and at a Bootcamp that promises this kind of thing, the ones I've seen do a week of one way lectures from past students who have no real system design experience. So TLDR: look at Formation.dev, Outco, Interview Kickstart, Scaler, Coachable.dev
