Problem framing
How did you turn a vague request into a testable question or useful decision?
Role preparation
Prepare data analyst evidence, not SQL trivia alone
Job titles vary. Read the actual vacancy first, then prepare examples that connect analysis, data quality, communication and a decision.
Four evidence areas
What your examples need to make visible
These are preparation areas, not universal scoring criteria. A marketing analyst, BI analyst and operations analyst can face very different work.
Data quality
What did you check, what remained uncertain and how did that affect the conclusion?
Technical method
Why was the tool or method appropriate, and what alternative did you reject?
Decision impact
Who used the result, what changed and how was the outcome supported?
Communication
How did you change the level of detail for technical and non-technical stakeholders?
Reflection
What limitation or mistake changed your later analysis?
Occupation boundary
Data analyst is not one standard job
O*NET lists Data Analyst as an example apprenticeship title under Statisticians and provides Business Intelligence Analyst tasks such as producing reports and collecting business intelligence. Use those sources to orient yourself, then use the employer’s vacancy to define this interview.
