IQVIA Sr. Consultant interview questions

The interview started with a phone screening with HR, then a case interview for the 2nd round, followed by another case interview. The case interviews were good but the final round with the MD was nothing impressive. After weeks of waiting for the result and hearing mulitiple deadlines, I finally heard the result via whatsapp from an HR person. It was extremely unprofessional and the HR person provied zero feedback. Extremely disappointed with the final end of the process but the case interviews were good and friendly.

3 sets of interview: 2 technical, 1 HR one exercise based on model report - interpretation of model results . technical question may be difficult for those who have lost touch with the basics.
