I reached out to a recruiter. She set up a phone screen and sent me a coding challenge afterward (the same one that everyone else received).

The phone interview was with one of their engineers and pretty much followed what others have described:

• Valid BST
• Product of array except itself
• Designing 2048

The onsite consisted of:

• One whiteboard session
• Lunch
• One whiteboard session
• A coding test
• One whiteboard session

Everyone was very friendly and seemed really smart.

The onsite was one of the harder ones I've gone through because they asked a variety of technical questions that weren't standard LeetCode questions and required a lot of thought.

k closest points to (0,0) merge 2 sorted lists of length n and m with only m extra space, n > m find largest sum of consecutive integers in array, then do it using 2 threads design DB tables so that adding an attribute isn't expensive integer division in < O(n) time create data structure to serialize XML/HTML question about dependencies and printing them out in order design a jigsaw puzzle and an algorithm to solve it
