A a friend of mine said he could recommend me to a junior DevOps role at the company he works in, but I’m interested mostly in back-end development and DevOps is not really something I like. The question is: could I use experience as a DevOps to later switch to back-end? Edit: more detail
True, but the distinction still holds value. If a company has a DevOps role defined, you can derive from that what kind of a company you are joining. For example, they hire based on marketing and not based on merits, which tells you something about the colleagues you can expect to be working with. It also tells you about how they structure work and that hierarchy and bureaucracy may play a bigger part in getting your work done than you might like.
Good point and an interesting take. As you said this could be a good signal, when taken in context with the other limited information we get as employment candidates, about internal development practices.
