Paths into IT and the skills that carry over.
“Working in IT” covers many different jobs. Some spend the day helping people with problems, some write software, some study data and some protect systems. Knowing what each role does day to day helps you choose what to learn first.
These entries describe common roles in plain terms, without salary figures or promises, and teach skills that carry across roles: version control, building a learning plan and explaining technical problems to people who are not technical.
Who it helps: Start here if you are deciding whether and where to enter IT, or if you already work in IT and want to build the skills around the technical ones.
