There are multiple rounds with their US and overseas teams. The interview questions are standard but detailed and heavily screwed towards engineering implementations. Some interviewers look tired and start right away with technical questions. Feel like more of an exam rather than collaborative discussion.

self introduction; easy coding (write a function to produce fibonacci numbers + complexity analysis + recusion/dynamic programming); deep dive into my own research; casual talk on the team and tasks;

The process started with an HR screening, followed by three technical interviews, and concluded with a final interview with the Hiring Manager. Overall, the process moved quickly, and each stage felt smooth and well-structured. My performance seemed solid throughout, and the discussions with the interviewers were generally positive and engaging. Despite this, I was ultimately rejected after the final interview.
