I got the telephonic call by them and had a chat about telling myself and my experiences. I got strictly rejected because of not mentioning things about my DSA and problem solving. They love codeforces and codechef. So if you don't say those words you are not going ahead.

2 x 45 minute interviews, back to back. Both interviews started with self introduction, leetcode (both easy), and behavioural + Q&A. One was done in mandarin and the other in englihs.
