Premium questions with real-world problems

The JavaScript Algorithms, Node.js, and SQL online test assess candidates' algorithmic thinking skills in the JavaScript language, knowledge of specific Node.js features, and their ability to use SQL.

It's an ideal test for pre-employment screening. A good Node.js developer needs to be able to solve problems using Node.js, and also use JavaScript to design and implement algorithms that are both correct and efficient, and to write and analyze SQL queries to access a database.

This online test requires candidates to solve coding problems in JavaScript and Node.js, 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

SQL Aggregation Select Public

Given the following data definition, write a query that returns the number of students whose first name is John. String comparisons should be case sensitive.

JavaScript Algorithmic thinking Dictionary Public

Write a function that, when passed an array and a target sum, returns, efficiently with respect to time used, two distinct zero-based indices of any two of the numbers, whose sum is equal to the target sum. If there are no two numbers, the function should return null.

For example, findTwoSum([ 3, 1, 5, 7, 5, 9 ], 10) should return an array containing any of the following pairs of indices:

  • 0 and 3 (or 3 and 0) as 3 + 7 = 10
  • 1 and 5 (or 5 and 1) as 1 + 9 = 10
  • 2 and 4 (or 4 and 2) as 5 + 5 = 10

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.
