I've been gainfully employed as a software dev since about 6 weeks after graduation, fist as an "associate engineer" then promoted to a regular engineer.
My bootcamp focused on Node/Mongo/Angular, but after I got my first job most of the work needed to be done in Rails. The bootcamp did not directly prepare me to work with Ruby, but it taught me how teach myself new skills and be okay with being in over my head. I was able to get up to speed after a couple months. I have gotten comfortable working with a lot of cool technologies since then - including Docker/Kubernetes, Kafka, and various tools for running distributed systems. Now I mostly work on the front-end of the product with React/Redux.
I feel comfortable working with much more complicated code than I did 2 years ago, and I keep getting good performance reviews.
I can say that going through the bootcamp definitely put me into the right mindset to be successful as a software developer. Often I was given vague answers left to figure something out for myself, which is pretty spot on to my current work.
From what I gather through Linkden and Slack, the top 2/3 of my cohort is in a similar situation, with the rest still getting Jr. level jobs and a couple who gave up altogether on the software thing.
