Tatsächliche Eingabe
- Raw experience
- Retail supervisor. Weekly rotas for 45 employees generated frequent corrections. Store managers owned availability data. I proposed and built an Excel workbook with Tables, XLOOKUP, SUMIFS and validation, tested it on one week, found that duplicate employee IDs caused wrong lookups, added a uniqueness check, then trained two supervisors. I maintained it. Correction logs averaged 12/month for three prior months and 5/month for three later months. Staffing policy also changed, so contribution cannot be isolated. One supervisor initially preferred the old sheet; I asked them to test two shifts and used their feedback to simplify the input tab.
- Interview question and competency
- Tell me about a time you improved a process. Competency: diagnosing a problem, using data, involving users, and sustaining a practical change.
- Answer constraints
- 90 seconds, Operations Analyst interview, UK English. Do not say I led a team, reduced corrections by a percentage, or caused the full reduction. Employee data details are confidential. Weak point: no formal experiment.
