ByteDance Algorithm Developer interview questions

It's not a good one, during the interview, the interviewer's network and laptop are both dead for more than 10 minutes. I'm patient and humble during the whole procedure and show total understanding about this issue and let him not worry about that. Even though I solved all coding questions and when I asked him what I can do to be fully prepared for such roles, he even said that I'm on the right track. Anywanys, I still got a no on the next day morning... That's QUICK, showing that he doesn't want to consider me at all...
