After learning how to keep servers safe and secure during your database administrator training, it’s time to put those skills to the test. While your training is great preparation for a job as a database administrator, first you’ve got to get past the job interview. And that means nailing some of the most common questions would-be database administrators get asked.
Though this isn’t by any means a comprehensive list of the questions you may hear, it will help give you direction and a better sense of what may be expected of you on the job. Here are three questions you might get asked during your job interview to become a database administrator.
1. What Kinds of Databases Have You Had Experience With Through Your Database Administrator Training?
Database administrators often work with a variety of different databases, such as MySQL, DB2, and Microsoft SQL Server. Having experience with different servers, either during your training or on your own time, is a great way to prepare for this question. The hiring manager may also want to know about your experience using both cloud databases and on-premise ones, so they can better understand how familiar you are with older and newer types of database infrastructures. This is an especially important question to prepare for since there are numerous kinds of databases out there, so be sure to describe your experience with each and the various duties you had. This question is also an opportunity to show off the experience you gained from your database administrator diploma and how it has prepared you for the position.
2. What is Oracle and What Tasks Do You Usually Have to Do With It?
One major database is Oracle, which you’ll learn about extensively in your database administrator training. Many companies will want to know how familiar you are with its programs and how they work. Oracle is a relational database which allows users to access data through SQL (short for structured query language). The Oracle server is secure and is able to perform automatic recovery of the database in the event of an instance failure.
Furthermore, they will want to know what kinds of tasks you can perform with Oracle, like installing software, creating databases, and performing maintenance and updates. The key here is to show how much you took from your training experience, since Oracle is a big component of it, and how well you understand the technology in general
3. If You Lost Data During a Database Migration, How Would You Handle It?
Here, interviewers are looking to find out how well you can handle stressful situations, troubleshoot, and problem solve under pressure. Since losing data is a significant pressure situation for any database administrator, it’s especially important not to lose your composure when this happens, and calmly think of strategies for recovery. Be sure to give the interviewers a walkthrough of your recovery process, and what you did to identify the root of what caused the data loss to begin with, as this will show how you’re able to think and act quickly in tense situations and fix database problems.
