Got a phone interview two weeks after I applied. Phone interview was simple. It includes some basic algorithm concepts and knowledge about python (I told him I am familiar with Python). Invited to the on-site interview a few days later and scheduled it one week later. There were five white-board interviews, about one hour each. Four of them were Leetcode questions(medium to hard) or similar. One was just asking some ideas about the technology field. Rejected one week after the on-site interview.

The interview mainly focused on Data Structures and Algorithms. Most questions were from Graphs and Dynamic Programming, with graph problems involving BFS and related traversal techniques. The discussion emphasized problem-solving skills, algorithm optimization, and coding implementation.
