The process is extensive, and even though I haven't reached the end, it starts with an HR interview to understand English level and previous experiences. To be approved, it's necessary to complete 4 LeetCode exercises (where I considered one for each level: easy, medium, hard, and challenging). I scored 2.5 out of 4 possible points and was approved for the next stage, which was a pair programming session where I had to solve a graph exercise.

It's truly a process and exercises that require dedication and familiarity with problem-solving approaches.

It was my first contact with this type of interview, and I had 1 week of preparation between each stage (it's possible to negotiate longer deadlines), but it wasn't enough for my case, where my knowledge was almost zero before the process.

They provide a lot of supporting study materials and simulation videos of the entire process. I recommend studying a lot, as the compensation package is indeed very robust and adequate for the level required during the process.

Describe a project for which you designed the solution and explain the reasoning behind the decisions made.
