I applied through a recruiter. The process took four weeks.

There were seven tasks between logic, algorithms, and coding. All of them needed deep thinking with careful answering, not just selecting a choice. They wanted the best choice. Overall, it's a good interview that means a lot for me because I know what I should focus on in the interview next time.

We want to implement a binary operator tritwise_min on lists. It takes the minimum in a "tritwise" manner. For example, tritwise_min([1, 0, 2], [1, 1, 1]) = [1, 0, 1] and tritwise_min([2, 1], [0, 2, 1]) = [0, 1, 1] (note that the third digit of [2, 1] is implicitly 0).
