I was recruited by a headhunter for the F1 team (Strategy Department).
1st round (HR): a phone call where you describe yourself.
2nd round (technical): 20 mins introducing yourself technically, 20 mins LeetCode Easy, 20 mins LeetCode Easy.
3rd round (technical): 20 mins LeetCode Easy, 30 mins LeetCode Hard.
4th round (onsite: technical + HR): 30 mins LeetCode Medium, 30 mins System Design, and 30 mins Behavioral.
I failed only because I couldn't finish writing the code for 3 out of 5 LeetCode problems in time.
The onsite interview is only paid for candidates coming from outside Italy.
Overall, it lasted 5 weeks.
