Premium questions with real-world problems

The Oracle PL/SQL and SQL online test assesses candidates' knowledge of SQL queries, relational database concepts, and specific Oracle PL/SQL features.

It's an ideal test for pre-employment screening. A good database admin or back-end developer working exclusively on an Oracle SQL Server database layer needs to be able to use Oracle's PL/SQL to create custom procedures and objects to interface efficiently with a database.

This online test requires candidates answer multiple-choice questions about PL/SQL, features of the Oracle SQL Engine, and write SQL queries that extract, combine, and manipulate data.

TestDome is trusted by businesses large and small

We’re top rated for our tests’ quality and reasonable completion time

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.
