I applied online. The process took 2+ months.

The process was good overall, maybe just too long. I started by submitting my CV and cover letter, which were quickly reviewed and accepted in 2 days. At this point, I undertook 2 sets of tasks of 4 hours each: the first assessing behavioral and logical skills, and the second one more focused on LeetCode-like algorithms.

After a month since the application, I had my first HR interview, and then a second one on problem solving after a week. The last step consisted of giving some references so they could ask additional questions, and they asked all 3 of them. At the end, a month after my last interview, I was told I wasn't being selected for the job, but they scheduled a call to give me deep feedback on all the steps of the selection process, which was appreciated.
