Ivanti Performance Testing interview questions

I got a call from consultant and went for interview ....Worst people... Worst interview process. No panel avilable so they asked some other avaialable employee who are not in performance testing to take interview. Interviewer doesn't even know ABC of performance..He was not even aware which tool this company uses for performance testing... Highly unprofessionals guy.. so roude while talking. The most funny part is they shortlisted my profile before 2 days but when I entered to interview room he said it's not matching to our current requirement. Interviewer is also not sure what exact requirement they have and what he should ask to me. I would suggest please never ever waste your time for this company interview instead do some creative work or spend you weekend time with family and friends.
