Applied Shanghai office online. After a month, I got called by a recruiter and arranged an interview three days later. Two rounds of technical interviews. The first round focused on technical questions, and the second one was more on my background and projects. I applied for NLP algorithms, so pretty basic algorithm questions, including BERT, transformers, regressions, kernels. Coding tests were a bit hard for me, but overall recruiters and interviewers were pretty nice and trying to walk me through an answer. Sad I didn't get the intern but the overall experience was great.
