I had one round with an software developer III. It was leetcode hard question. Question: Merge two sorted arrays. Platform was hackerrank. Just one behavioural question and one leetcode question. Interview went well.

2-3 Easy Leetcode questions, they ask about your coding experience, struggles you faced, and such. Very critical of the code you write, they will ask questions about everything, every function you write, very important you write the most optimized best solution.
