No chat with the employer post CV acceptance; you are immediately moved straight onto an online technical test stage. The technical test informs the user about anti-cheat measures and there is no ability to copy and paste into the browser IDE. It is not stated, but heavily implied, that googling or using anything outside the browser IDE tab is not allowed.
The online test consists of multiple-choice questions and coding challenges. All are countdown timed with varying limits. Time includes reading time and the time to click the submit button to register an answer.
Unless you grind online technical tests on the regular, you will struggle to pass this test. There is no opportunity to be evaluated beyond a test score; it is not a real-life working scenario.
Some multiple choice, some coding challenges
