I applied online.

There were five online tasks, ranging from 20 minutes (the shortest) to 90 minutes (the longest). They were ridiculously easy questions that I am quite positive I answered correctly, as they were simple logic questions. Nonetheless, I did not receive a job offer.

One question was about two chickens, A and B, that lay eggs each day with a specific table of probabilities. With probability P_1, they both lay eggs; with probability P_2, chicken A lays and chicken B does not; and so on. Then there were a lot of checkbox questions about the expected number of eggs laid in a week and such.

Another question was about writing functions in Python to do operations in base 3.

A third question was about two people, A and B, playing a game. The game consists of selecting alternatively all the numbers between 2 and a given N. The person selecting a number would get as points the number of prime divisors (with multiplicity) that are in a given set S. The questions were about who won and with how many points.
