Method
Practise a two-minute answer: question, source/grain, method, validation, finding, limitation.
Worked example
For the retail case: completed sales 300→400 EUR; verified unique orders and exclusions; report 100 EUR/33.3% increase while avoiding a causal claim. An interviewer can inspect the query and output.
Practice
Record yourself locally or rehearse with a friend. If asked about an unfamiliar tool, state your experience accurately and explain how you would investigate.
Self-review
Check accuracy, relevance, evidence and clarity. Resume guidance and examples are for learning and preparation only. They do not guarantee interviews, a job offer or employment.
Try the activity before reading its reference. Keep your sources, commands and assumptions with your work. Companion activities are unsaved self-practice and do not award a certificate or change lesson progress.
