Experience
Recent relevant roles, tasks and duration of practice.

A useful introduction is short, honest and specific. It shows real tasks, tools and responsibility, not only job titles.
A recruiter can evaluate experience more easily when it is described through actions. Instead of listing job titles, choose several situations that show what you actually did: repaired a type of equipment, maintained records, organised a shift, managed a vehicle, trained staff, worked with customers or analysed data. Add the outcome and scale when that does not expose confidential information. This shows both knowledge and the level of independence. Experience from another industry can still be relevant if it demonstrates transferable capability such as attention, planning, technical thinking, communication or responsibility.
There is no need to call yourself an expert when a skill was only occasional. Explain what you did independently, what you performed from instructions and where you needed a senior specialist. This creates trust and helps estimate training needs correctly. If a tool has not been used for years, say so. If a certification exists but practical experience is limited, say that too. Exaggeration can lead to a role whose expectations are far above current readiness. An accurate profile makes it easier to find an appointment where strengths can be used immediately and weaker areas can be developed systematically.
A gap does not always need to be hidden. It can become part of a plan: refresh the skill, take a course, practise under supervision or begin with an adjacent task. Distinguish between “never done,” “done long ago” and “can do with support.” These represent different levels of readiness. If you are motivated to learn, describe what you are already doing—reading documentation, taking a course, practising or returning to hands-on work. Concrete action shows motivation more convincingly than the broad statement that you are “ready for anything.”
When describing previous work, do not disclose trade secrets, passwords, other people’s personal data, protected technical configurations or restricted service information. Competence can usually be shown with general context: the type of system, scale, your task and the result. If an example involves sensitive data, remove identifying details while preserving the professional meaning. Full personal documents are also unnecessary in an open first contact. The introduction should describe the professional profile; evidence and documents should be transferred only at the appropriate official stage.
It is useful to have two versions of your introduction. The short version takes 30–60 seconds: who you are, the main background, two or three strong skills and what you want to discuss. The detailed version is for the conversation: specific tasks, tools, results, limitations and questions. This prevents overloading first contact while keeping you ready to expand when asked. Both versions should be consistent in substance; brevity does not mean hiding important facts, and detail does not mean sending every personal document.
Your strongest and most relevant examples.
Team size, years of practice or workload without sensitive detail.
What requires learning or refreshed skills.
Which fields you want to compare and why.
Recent relevant roles, tasks and duration of practice.
Equipment, software, documents or methods.
What you improved, organized, repaired or completed.
The conversation should help both sides assess suitability.
