Ixia Solutions Associate Project Manager interview questions

HR executive took my PM technical round, and although I have all the right answers I got rejected. Later on, with the same knowledge, I landed a much better job with a 3x hike. When I asked junior HR, she told me my answers were too deep and confusing, I mean sure they are but for an HR executive as he will not have in-depth knowledge/understanding of PM terminologies. Please ask senior PMs or someone from the Management team to conduct the interview instead of wasting the Candidates' time. If you are interviewing please ask for PM for conducting the interview
