What Is a Database Administrator?
A database administrator is a data expert who monitors, secures, and ensures the free flow of information in a database management system. They protect the database from external and internal threats. They usually work with companies that process large volumes of data and complex datasets.
Database administrators install systems to protect data from external parties. They also create access points for different levels of an organization. This way, only those with security clearance have access to specific datasets or transaction logs.
Answers to the Most Common Database Administrator Interview Questions
There are different categories of database administration interview questions. The most common categories are technical questions, behavioral questions, and general questions.
Top 5 Technical Database Administrator Interview Questions and Answers
These technical questions are the most important for every aspiring database administrator. The technical interview gauges your conceptual understanding of the field. Answering these questions correctly can demonstrate your technical knowledge of database management and administration.
Our Company Requires the Installation of a SQL Server. What Do We Need to Know?
Since SQL Server is common in the industry, your interviewer will want to test your knowledge of it. You should ask the interviewer questions to determine if SQL is an ideal fit. For example, you could ask whether the company’s current cloud system is compatible with SQL, which type of SQL the system supports, and whether the company has any security specifications.
It will also help to mention the types of SQL and explain why compatibility is important. The five types of SQL Server are Express, Enterprise, Developer, Standard, Web. Compatibility is important because it prevents disruption to daily business activities.
Which Third-Party Database Tool Would You Recommend as the Most Ideal?
With this question, the interviewer wants to find out how comfortable you are with third-party database administration tools. It is important that your answer tells the interviewer that you do not restrict yourself to using one third-party tool alone. So, you should mention more than one in your response and make sure the interviewer knows how flexible you are.
Navicat and MSAccess are probably the top two tools for solving database issues. Navicat is a database software program that can connect to multiple servers at once, and it is also efficient in backing up large volumes of data. Microsoft Access (MSAccess) is another third-party tool. Users who value flexibility and user experience above all else prefer MSAccess.
If the Database Management System Suddenly Crashes and You Lose Data During a Migration Project, What Would You do?
This question is designed to test your knowledge of data loss protocols and data recovery tools.

If you have never used a data recovery tool before, answer the question based on your theoretical knowledge.
You can begin your answer by stating that you would try to salvage whatever you could from the database backups. From there you could talk about your troubleshooting and data recovery tool of choice. A good one to mention is Stellar Phoenix SQL Database Repair. It has a user-friendly graphical user interface, and it’s fast, easy to use, and compatible with most servers.
What Is Structured Query Language?
One of the first steps in a database administration education is to learn SQL. The interviewer asks this question to know if you have a fundamental knowledge of SQL.

You can say, for example, that SQL is the gold standard for interacting with relational database management systems (DBMS), and that it is most commonly used to update data on the DBMS and retrieve lost data. SQL gives users almost limitless opportunities to interact and work with data. SQL is also an ideal choice for ensuring transaction security for your business.
How Many Database Servers Have You Tried and How Would You Describe Your Experience?
This question is meant to assess your flexibility and confirm the information on your resume. State all the database servers that appear on your resume and offer a little background information on your experience with one or two.
If you’re familiar with Oracle Database, Microsoft SQL Server, PostgreSQL, and MySQL, for example, you can speak about some of the differences.

Tips to Prepare for a Database Administrator Interview
1. Pay Attention to Non-Verbal Cues
During face-to-face interviews, the interviewer doesn’t just listen to what you say. They watch your body language, movements, and other forms of non-verbal communication. So, if you’re asked about how to spot anomalies in a SQL server, you should answer the question confidently. Try not to act nervous, even if you are.
2. Listen Attentively
The listening component of communication skills should not be overlooked. Don’t cut your interviewer off when they are speaking. Wait for them to finish and respectfully ask for clarification from the interviewers.
Not all the information they offer will come directly. If you’re not listening attentively, you might miss a crucial point that can impact your chances of success. Make sure to listen and pay attention to the subtext of whatever the interviewer is saying.
3. Maintain Professionalism
Your interview is your chance to make a strong first impression. If you are attending an interview in person or over a video call, you should dress well. Even if the company has a casual dress code, don’t dress too casually for your interview. Professionalism also includes how you carry yourself. Don’t be someone you aren’t, but do try to command the interviewers’ respect.
