8 titlesWhat the report looks like for Database Admin
- The situation in one sentence: where, what was short, and by how much.
- The decision that was yours rather than the team’s, and what you chose not to do.
- One number or one consequence that shows it worked.
Every competency is scored out of five with a line you actually said as evidence, and the weakest answers are rewritten as structure and specifics, never a script.
What Database Admin interviewers keep scoring
Query & database performance tuning
Diagnoses slow queries and database bottlenecks from execution plans, wait statistics and metrics, and fixes them at the right layer (index, query, schema, configuration).
Backup, recovery & high availability
Designs and tests backup and recovery to meet RPO/RTO, operates high-availability and replication, and can recover from corruption, deletion or site loss.
Database security & data protection
Controls access with least privilege, encrypts and audits sensitive data, and supports compliance with POPIA/GDPR and audit requirements.
Schema design & safe change management
Advises on data modelling and indexing, and deploys schema and data changes to production safely with review, testing and rollback.
Monitoring, capacity & automation
Keeps databases observable, forecasts growth and resource needs, and automates routine administration.
Incident handling & root-cause analysis
Restores database service quickly under pressure, communicates clearly, and drives root-cause fixes rather than repeating firefights.
Partnering with developers & application owners
Works with developers as a partner: reviews designs early, explains database behaviour, and enables safe self-service rather than gatekeeping.
