Career-change resumes are screened for honest transfer: which past proof matches the new posting. A fake job history fails the first call.
Lead with a target title and a short summary that names the bridge. Then reorder bullets toward the new job’s requirements without rewriting dates or employers.
Training and projects can support the bridge. They do not replace a role. Say what is coursework when it is coursework.
Usually no for ATS. Keep chronology and change which bullets you emphasize for the target role.
You can shorten old unrelated roles. Do not create gaps you cannot explain or invent titles.
