HARMAN interview questions

The interview started with my introduction and few basic questions related to HTML and JS/Typescript. Specific to my interview - the interviewer was not able to explain the problem statement of a program(he wanted to see the use of "promise" in god knows what way) and talked as if I was inefficient in understanding , moreover in a rude and adamant tone of voice. This changed my pov regarding the company and its employees and instantly I felt a dislike about the whole interview process. So a couple of HTML and JS questions and then the above scenario happened, which made me think that further interview would be unnecessary as I dont want to work there anyway. Voluntarily I opted out in between the interview. Save your time and frankly dont appear for interview over here for any role and any amount of money.

Difficulty level was easy, should have good concept with c++ and good programming skills for c Next round was managerial round, asked about os concepts,process ,threads, process synchronization, c and c++
