Walmart SSE | Great and Self-conceited interviewer

I recently went though multiple rounds of interview at walmart tech. There were around 4 rounds for a position, I could not clear this interview process. Later they pushed my profile for a different team. During this process I have seen both side of interviewers.

Great set of interviewer

• Round 1 : interviewer was very polite and supportive. this was coding round he asked 2 questions. Sliding window and graph traversal.
• Round 2 : System design, same as previous interviewer. It felt as if i was having a discussion with a colleague. Question: to design Auction system.
• Round 3 : HLD LLD, Interviewer was neither polite nor rude, neutral kind of guy, Quesion : design task scheduler.
• Round 4 : Hiring Manager, Interviewer was neither polite nor rude, neutral kind of guy, behavioural interview questions.

Self-conceited interviewer

• Round 1 : HLD LLD, one of the built-in java API class and a system similar to Redis. Everytime i write a single line he would comment saying why are you doing this, he would not let me complete a thing. On top of that he kept repeating this line, Say my name is John, then he would say "John really, you really want to do this?" I felt this was degrading.

Final result was rejection in both interviews, To be honest, I know i am bad at tech right now, with the little time that I have I am studing. If i would have gotten offer from second interviwer, I would have joined out of desperation, But I surly would not like to work him.
