Fast and efficient, everyone is friendly.
The interview was fully techinical, no background or behavioral questions for me. The style is very collaborative — asking for hint in a proper way would be considered a plus I guess.

First round was online, one round of 1hr class design questions.
Given a class interface, you need to implement it with another given class interface. My question is like a general tree question.
You kinda need to go far enough to get to next round, so if you're too slow or have trouble solving easier parts, you cannot make it. I didn't move on.
