Database Administrator
A developer asks for full admin access to the production database to debug an issue. How do you respond?
What the interviewer is looking for
- This question tests database security. Applies least privilege, role-based access, encryption, auditing and safe handling of production data.
- Strong answers: Understands the need, offers least-privilege or read-only access, a replica or masked copy, time-limited access with auditing, and follows policy.
- Likely follow-up: What if it is an emergency in the middle of the night?
Another way it may be asked: Someone on the dev team says they need complete control of the live database to fix a bug. What do you do?
A structure to follow: Answer, explain, example, limits
- Step 1
Answer
Give your direct answer in the first sentence so the interviewer knows where you are going.
- Step 2
Explain
Say how it works or why you would do it that way, in plain words before jargon.
- Step 3
Example
Anchor it in something you have actually done or seen, with the detail that shows hands-on experience.
- Step 4
Limits
Say when your approach would not be the right one. It shows judgement.
This is guidance on shape, not a script. Use your own real experience and facts; never invent details to fill a gap. See the STAR guide and answer frameworks.
Common slips
- Reciting a definition without showing you have applied it.
- Using terms you cannot explain if asked a level deeper.
- Claiming experience beyond what you can discuss in detail.
How to practise it
Say the answer in 90 seconds, then answer the follow-up as if it were a new question.
