To set yourself apart during the Smart Energy Water hiring process, keep these practical, insider tips in mind:

• Clarify the job description early: Because some teams at SEW focus purely on manual validation while others require test automation, explicitly ask your recruiter in the first call about the exact balance of manual versus automation work expected.

• Structure your scenario answers: When asked to test a scenario, don't just list ideas randomly. Use a structured framework: start with functional positive flows, move to negative scenarios, then cover security, usability, and performance.

• Be ready for pen-and-paper SQL: Do not rely on IDE auto-complete features. Practice writing clean SQL joins and aggregate queries on paper or a simple text editor, as you will likely need to write them live without technical assistance.
• Emphasize your data validation skills: Utility platforms are highly data-centric. Highlight your experience in validating complex data flows, migrations, and database state changes, as this is highly valued by the hiring managers.
