HARMAN interview questions

The HR ghosted me after inviting me to interview and didn't even bother following up even though I had reached out multiple times to set up an interview. This shows a complete lack of disregard of a candidate's time and lack of respect.

Smooth and straightforward process. 3 rounds of discussion followed by managerial debate. The interviewer is like to have a discussion but not like only questioning. All rounds were easy and salary is as per market standard not above.
