IQVIA MSBI Developer interview questions

I had applied through LinkedIn, got a call from the HR and the interview was scheduled. I had 2 rounds of interview. The first interview was technical, the interviewer was really good. The second round was kind of managerial round. They asked me scenario based question and in the same call had an interaction with the manager. Everything looked good and well. worst part is I have been trying to reach to the HR and she doesn't bother to respond neither to calls or mails. Any update from the company would have been of great help, this is so unprofessional. The interview was good and the manager sounded so positive with their words. At least a rejection mail would have given some closure. Very disappointed.
