I was given a behavioral assessment, which I passed.

After passing, I was contacted by a recruiter to start the process of the four-round panel interview. For the four rounds, I was given a whole month to prepare.

The first three rounds were technical, and they could vary from medium to hard on LeetCode level.

• The first round was recursion.
• The second round was a tree/graph.
• The third round was map/string.

The last round was "googliness," and that was behavioral.

The difficult question was about filling buckets of water with the given information.

It is a hard-level question from LeetCode.
