This company may be familiar to everyone. I found it quite difficult after the interview, but the advantage is that the interviewer will give you some positive prompts along the way to guide you to come up with ideas to solve the problem. 15 minutes after the VO ended, I received a verbal offer in my email, because he saw that the previous feedback was more positive and my database ability was okay, so he was more relieved to me. Later, it took us more than a month to talk about the offer, and finally I signed with him.
