I applied online. The process took 3 weeks.

The interview consists of multiple tests, done online and graded by people, then multiple online in-person interviews that were 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. There were seven questions in total, with a half-hour time limit for each question. The second set of tasks was LeetCode-esque programming challenges. I received two problems, with an hour and a half for each.

Every individual question in all the above-mentioned 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 assessments. I haven't made it that far.

The first seven problems on the online test were general problems:

• Reading comprehension: A text is given, and then they ask questions about the contents.
• English language assessment: A slightly more complicated text is given, and the answers offered aren't exactly obvious, and are there to gauge the level of your understanding.
• Logic puzzles, like: if you move a unit south, then east, then north, you end up where you started from, where are you?
• Statistical reasoning questions: you have some metrics for different time scales, you need to compare them and understand their relationships to not give a wrong answer.
