Premium questions with real-world problems
The MySQL and SQL online test assesses candidates' knowledge of SQL queries, relational database concepts, and specific MySQL features.
It's an ideal test for pre-employment screening. A good database admin or back-end developer working exclusively on a MySQL server database needs to be able to use features specific to MySQL to interface efficiently with the database.
This online test requires candidates to answer multiple-choice questions about MySQL and to write SQL queries that extract, combine, or manipulate data.
TestDome is trusted by businesses large and small
We’re top rated for our tests’ quality and reasonable completion time
"TestDome doesn't take the candidate an inordinate amount of time. It simulates working pressure with the time limits."

Select all the true statements about this method of pagination.
(Select all acceptable answers.)

Practice your skills.
Pick the number of tests you need.
Pass/fail grouping
Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.
Full customization
We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.
Cheating protection
Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.
Candidate reporting
Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
