What systems does Merreo have in place for cheating prevention?

We disable copy-paste functions during an assessment. This minimizes the risk of test questions being shared online.
Merreo questions are adaptive, and no two candidates will see the exact set of questions because of the size of the question back for each test.
Merreo also randomizes the order of the choices each time the same question shows up.
Candidates won't know ahead of time which tests are in their assessment. Candidates only learn which test they're taking at the start of the test. At that point, the timer begins, and the candidate won't be able to leave the assessment without you knowing.
Tests are timed and come with a bit of time pressure, allowing no time to look up answers.
We detect if they exit full-screen mode at any time during the assessment.
We also detect if their mouse leaves the assessment window; for example, to browse the internet on a second screen. If the mouse leaves for more than 50 seconds per test, that assessment will get canceled.
We take snapshots every 30 seconds using a candidate's camera. This is done to verify that the candidate is the one taking the assessment, without any outside help.
Our anti-cheating monitor will alert you if we detect any red flags from a candidate. If there are, it doesn't necessarily mean the candidate is cheating - use careful judgment.
