McAfee Software Development Engineer In Test interview questions

HR contacted me and there was initial phone screening and after that, I had 4 onsite interviews at McAfee office (Bangalore). After clearing all, there will be a director Round. The Onsite Process took one whole day and the interviewers were polite and helping in solving the questions, reviewing the code. There was a lot of delay on the whole process, I had all the above rounds and I tried multiple ways to contact the HR but there is no response. I was annoyed as I did not even get my feedback after all the rounds. After some 20 days, HR contacted me and told me that I cleared all the rounds.
