Cornerstone Building Brands interview questions

The interview was in 4 stages. 1st was HR Screening Interview. 2nd stage was with Hiring Manager. 3rd stage was with a panel of 4 Directors. Last stage was supposed to be with the VP but it was cancelled at the last minute. The interview experiences were great all through as I interviewed with highly knowledgeable and professional people whom I was looking forward to working with, however thr manner in which the last stage was canceled after interviewing over a 2 month period, was less than professional. An unknown person just emailed me to say she was now in charge of the the recruitment and that the role had been canceled. It was disheartening and leaves much more to be desired.
