I had onsite recently with google and had 3 rounds as part of that . I cant share exact question, but can share leetcode question which mostly or completely resemble onsite interview:

First round :

https://leetcode.com/problems/regions-cut-by-slashes/

Second round :

https://leetcode.com/problems/earliest-second-to-mark-indices-ii/description/

Third round :

https://leetcode.com/problems/longest-increasing-subsequence-ii/description/

They expect to give most optimal answer , for example in third round . I did solved it by O(n2) but interviewer expected to solve it in O(nlong) time.
Surprisingly most interview was taken by non-asian people although I applied for asia role. Faced issue as some interviewer accent was tough to understand
Good luck to everyone
