Premium questions with real-world problems

The C#, Microsoft SQL Server, and SQL online test assesses candidates' knowledge of programming in the C# language and their ability to use T-SQL and SQL.

It's an ideal test for pre-employment screening. A good C# developer needs to be able not only to solve problems using C# but also to write and analyze stored procedures and SQL queries.

This online test requires candidates to solve coding problems in C#, write SQL Server procedures, and 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

  • The day of the month the item was bought [1-31].
  • The number of the month the item was bought [1-12].

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.
