Simplilearn Solutions Software Development Engineer (SDE) III interview questions

My friend refers me here. I went through 2 rounds of the process. 1st round was related to basic js knowledge + 1 coding question. The second was also the same but a little bit difficult compare to 1st round. I have answered almost all questions correctly. Interviewer feedback was also positive. I don't know what happened at last HR told me we can't go further with your profile. At least give feedback to people so they can understand why you are rejecting them. Anyway, I am happy. I don't want to be a part of an organization where the interviewer has lacked knowledge and try to win the arguments to show that they know the most everything.
