I applied online. The process took three months.

The interview process was divided into three stages. The first stage was the CV review, the second was an online coding task, and then I had three technical and behavioral interviews in one day. Each interview was forty-five minutes long, and there was a fifteen-minute break in between. The structure of each interview was the same. For the first fifteen minutes, we talked about my personal projects, university, and other topics. After that, we moved on to solving some LeetCode problems, where they wanted to see my thinking process and my coding skills. Meanwhile, they were also asking some technical questions, mostly about data structures and algorithms.
