After you apply online without your CV(strange), they send you an invitation link to complete a GMAT test-based questionnaire. The level of the question is based on conditional probability, multi-linear equations, geometry, the minimum or max value of a function, pseudo-code.. etc. I didn't pass the test because the "test score did not meet our criteria". Criteria that nobody knows, in fact, they don't give you any test results or tell you what the minimum score to pass to the next stage is. The process lacks transparency and communication, I could imagine the company's environment if this was the start.
