Start with repeated patterns
Look for the kinds of problems you solved repeatedly, not just job titles.
Transferable skills
Identify transferable skills in a way employers can actually understand
The problem is usually not that you lack transferable skills. It is that you are describing old work in old language instead of translating it into decision-relevant value.
Translate into target-language
Frame your experience using the needs of the destination role.
Support with evidence
Use examples that show scope, judgment, outcomes, or complexity.
