I had a technical phone interview first. They asked one basic algorithm question.
After that, I was invited for an on-site interview.
It lasted 4.5 hours, and I interviewed with 4 engineers and one manager. Each engineer asked me 2-4 algorithm questions. I answered all of them very well.
However, they felt my explanations were not good because my English was not strong. They still rejected me in the end.
The manager asked me what I know about the company.
Also, one engineer asked about the rotation of the BST. I have done it before, but it is hard to solve this quickly, as it has many cases to consider.
