You can take any of our public tests for free, you don't need to sign-up. Just choose any category in our Library and you'll see tests above the list of questions. Select the test you'd like and click the "Take a Practice Test" button.
If you were invited to a test by an employer, you should use the test link that they sent you.
Each question has it's own time limit. When the time limit expires, your last chosen answer will be automatically submitted.
Coding questions allow running your solution as many times as you'd like to see if it passes the test cases. For these questions, your highest scoring answer will be automatically submitted when the question time expires.
This also means that it's not possible to go back to a previous question after an answer is submitted (or the time expires).
For coding questions, we recommend having an IDE ready. You can use whichever IDE you prefer and then copy/paste the code into the coding area on the test question.
We don't prevent the use of online resources during tests. However keep in mind that some employers may enable test proctoring (which includes both webcam proctoring and screen sharing) to prevent cheating.
