For software devs, I haven’t found sector to chain you nearly as much as the stack. I’ve been in Microsoft since the beginning of my career (.NET and more recently with Angular) but I’ve switched sectors from publishing, to insurance, healthcare, supply chain, education… All of those were in .NET. It probably would’ve been harder to get a job in the same sector but a different stack (Java or whatever). So… I’m glad I didn’t start in COBOL is what I’m saying. :)
