Arcadia Senior Project Manager interview questions

Recently I attended an interview, but I lost this opportunity only because of the interviewer...This interviewer looks a bit aged and whatever I say he replies back saying he got confused...he seems outdated and the interview experience was quite bad because of his confusing behavior....Not sure how he is working in this company with this confusion syndrome...Example: I told him I am parallelly working on 5 projects, and his response was 'I got confused how do u work parallel in 5 projects..' also he is sticking with some questions like how I am getting these many projects.....which doesn't make sense at all...Lucky I have not got selected here Seems he is a fake interviewer...Management has to look into this..
