Process
First, there's the HR interview, which is basically an introduction of each other.
Then, there's the code challenge. It's not very difficult.
After that, there would be a phone screen and onsite interviews.
Questions
The phone screen interviews are just about basic CS questions. It seems like they had a list of questions. I think I provided the correct answer for all of them, but they still failed me.
