Blue Yonder Devops Engineer interview questions

It was extremely pathetic. After 2 technical round which went awesome, there was a manager/director round which went more than 1.5 hrs. Everything was good. No response for 15days where on the interview day itself HR told we will pay you good as tech rounds went very good. When I tried to follow up with HR, I got to know they have hold the position. Man if you are not clear about the requirements then y do you waste candidate’s time. Very unprofessional. Would suggest no one to attain interview.
