At Code Fellows we have quite a few students who use boot camps to switch stacks or they have legacy CS experience that they are getting back into. We also have a lot of newer folks. One of the things that we've seen at Code Fellows is that incoming students need to have a Foundational understanding of data structures, algorithms, and data types—and also a experience in the stack they are going to take a boot camp in. If they have these ingredients and relevant experience then they can take off in those 8 weeks and be prepared and inspired to keep learning, growing, and get a job. We are super clear that this is a HARD life long process—and that's part of the fun/agony of it all :)
