IQVIA Sr. Consultant interview questions

Initial HR screening interview. Followed by 2-3 interviews incl. personal fit and case studies - with interviewers on manager and principal level. It also included a mathematics/analytical test. Interviews taking place in person and on one day.

HR person called me in the night around 10.00 pm. When I called back she ask that she will connect back at 9.30 am next morning. Did not receive any call. I texted, called but no response. In the evening she called around 8.40 pm and said are you available for interview. I was interested in the position that’s why I agreed but I guess this HR lacked even screening interview experience.
