Interview questions worth rehearsing

With the thing the interviewer is actually listening for

A critical query got slow overnight. How do you investigate?

Check execution plans, statistics, recent changes, and blocking. A structured path from symptom to cause is what they are grading.

Walk me through your backup strategy and how you verify it.

Cover full/differential/log backups, RPO/RTO targets, and regular restore testing. The verification part is where weak candidates fall down.

How do you decide what to index?

Base it on query patterns and measured impact, and mention the write cost of over-indexing. Showing you remove indexes too is a good sign.

How would you design high availability for a critical database?

Discuss replication or availability groups, failover testing, and what the application must tolerate. Note that HA is not backup — they solve different problems.

A developer wants direct production database access. How do you respond?

Show least-privilege instincts with a service mindset: offer read replicas, audited access, or better tooling instead of a flat no.

Tell me about a data-loss scare or recovery you performed.

A calm, honest recovery story — what was lost, what was restored, what changed after — demonstrates exactly the judgment this role exists for.

05

Resume tips that move the needle

For database administrators specifically — generic advice costs you here

01

State the database platforms and versions you ran, with the size and count of databases managed.

02

Quantify performance work: query times cut, storage reclaimed, downtime avoided during migrations.

03

Highlight zero-data-loss recoveries or successful DR tests — recoverability is the core promise of the role.

04

Show cloud migration experience (RDS, Azure SQL, Cloud SQL) as most DBA hiring now expects it.

05

Mention automation of routine maintenance; it signals you scale beyond hand-run scripts.
