Very talented in wasting time and efforts. The recruiter never gives feedback after each round. Although all my rounds went very well. I got rejection for no reason. Literally "Thank you so much for bla bla, we have decided to move with another candidate." The process took 4 weeks due to the recruiter not being organized and responds once per week. All interviewers spoke broken English which is something really odd to me. One of the interviewers feared to handle an interview in English and had to reschedule 3 times yet he didn't make it by the end. Interviews got scheduled twice few minutes before commitment date/time specified a week earlier. Questions were leetcode style for the technical round (1 DP HARD, another is very useless just implementation, so I don't even consider it medium). I will not be able to talk about system design as this will expose my personality. Overall, please avoid applying if you don't speak Mandarin. Your chances are too low.
