The interview consisted of 7 tests, each lasting 30 minutes. The time only ticks when you start the test, so you can choose the time of the day/week when you feel the most comfortable to do as many as you want in a row. Tests were of logical nature and I personally found them very interesting - each test had a storyline and a couple of questions from time to time as story progresses. On average, each test has around 6-7 questions.

The interview consists of multiple tests (done online, graded by people), then multiple in-person (online) interviews (technical and cultural). The first set of tests was concerning a broad spectrum of tasks and abilities(??), from reading comprehension, to rational reasoning and some statistical reasoning. Seven questions in total, half an hour time limit for each question. The second set of tasks was leet-code-eque type of programming challenges. I've received two problems, an hour and a half for each. Every individual question, in all the abovementioned tests, is timed, but there isn't a time limit to the test as a whole (meaning you could do one 30-minute question a day, for a week). The next few interviews are supposed to be more in-depth technical assessments, as well as general motivation and cultural assessment. I haven't made it that far.
