I applied online. The process took one week.

I was sent an email asking for an e-test, specifically mentioning that every action on the browser is being saved. I guess that's a protection against using a GPT for help.

Almost all the problems were about what could be deduced given a situation. For example, given an inheritance graph of several classes, a function that takes in two arguments of these classes, and some samples of the function, what can be deduced? Can they be of the same class, or do they have to be different? In the same vein, given three DB tables with a specific structure, how many reads to the DB are needed to determine the first purchase made by a user? How about the second purchase? By reading only the two tables, can we deduce the average purchases made per country? The last one was about a code in a pseudo-language, and we had to deduce: is it an increasing function if the values increase after a value? What does it return at a given integer? How many times does the loop inside run?
