Data analyst and data scientist titles overlap across employers. One organisation may separate reporting and modelling clearly; another may combine tasks in a broad role. Ask what the person will actually do before choosing training or deciding which title fits your experience.

The questions below are a comparison framework, not a universal definition imposed on every employer.

1. What problem will the person work on?

Ask whether the priority is explaining current performance, investigating a question, building a predictive system or another task. A title without the business question gives little guidance about the evidence you need to show.

2. Which methods are genuinely required?

Read the actual requirements for statistical reasoning, querying, programming, experimentation or modelling. Do not assume every analyst role is non-technical or every scientist role uses the same methods. Identify what you can demonstrate and what remains a gap.

3. What does the person deliver?

Compare a report, dashboard, analysis memo, model or operational system. Ask who uses the output and how its quality is reviewed. A project can demonstrate one type of deliverable without proving readiness for every other one.

4. Who owns data preparation and operation?

Clarify the relationship with data engineering, product and operational teams. A role may include extensive preparation or ongoing monitoring. Do not infer the support available from the title alone.

5. What level of experience is expected?

Check the responsibility, independence and domain knowledge. A “junior” label can still have specific requirements, while a broad title does not necessarily imply seniority. Ask how learning and review will be supported.

Choose the next practical step

Compare several live descriptions side by side and prepare a question for each unresolved difference. Use analyst portfolio projects to demonstrate work you actually understand. The tech role map provides demand context, but broad occupational demand is not a guarantee about an individual role or an applicant's readiness.
