Interview took about 1 week. Had three rounds. 1. Monjin(30 min) 2. L2(1 hour) 3. L2 (Again)(30 min) All questions was on given topics: Spring boot Web services DSA Design pattern Networking Every round had one question on DSA, which consumed approx 20 min of my time. In first round they asked me questions on Spring boot(Beans, factory, properties file, etc), design pattern(Observer pattern), DSA. In second round they asked to some more questions on Spring boot, design patterns and DSA. In third round they asked me about Spring boot design patterns, DSA and networking. First two rounds for me was good but third round was very bad, and when recruiter told me that I need to prepare myself and asked me to do I have any question for him. At that Time I literally wasn't having anything in my mind except that I need to prepare myself and I told him same that I need to prepare and after that I will again interview in this company and I showed him some of my positives like I noted down those questions of which I failed to answer as I always search for the answer for those question after the interview. May be these was some of the things due to which he selected me.

30-minute phone screen about the role and my background 1 hour of technicals: 30 min of coding + 30 min of Right/Wrong Question and Answer 1 hour with a C-suite executives about previous experience The funniest thing is that the software engineer had never heard of IOT, and Zhongjing Yao was very "by the book" about his answers. He was distracted during the coding portion, typing away at slack messages. They then ghosted me.
