I went till the virtual interview and was rejected after that. Posting my experience here so as to help the others as the posts here helped calm my nerves a lot.

I am skipping the focus on OAs since it was more or less the same. To give an idea of my performance in them - I answered 5 of the 7 debugging questions, passed 13/14 test cases in the first and 18/22 in the second question of the coding round. Both of the questions were in the discussion post.

The virtual interview was of 45min wherein the interviewer came in 5 min late and was yawning in between.
He started with explaining me the process and started with 2 behavioural questions -

1. Did you take any decision without consulting your supervisor? This followed with some related questions like if your manager was happy later on etc.
2. Did you miss a deadline?

Focus on specifics in behavioural question. I realize now I was speaking quite vaguely and was interrupted and asked to explain in specifics.

Coding question -

Given a binary tree, print its immediate right neighbor (level wise)

This was a simple question and I started implementing it in queue.
To be honest, Leetcoding is not my forte and I was stuck in it and the interviewer hinted me and I was able to solve it. He later asked me the time complexity.

The interview ended with me asking him questions about his work and the team.
