IQVIA Programmer/Analyst interview questions

Someone scheduled an interview and then canceled it on the calendar, citing "the position was closed". No human interaction other than the original scheduling email. This is not my first disappointing experience with IQVIA’s hiring process. I have faced multiple issues, including recruiters calling for the wrong person and instances where I was contacted, only to be told shortly after that I was unqualified. The process has been consistently disorganized.
