Worried About Silence After a Successful Technical Interview? What Should I Do Next?

Dear all, my technical interview was a telephonic interview. After the interview was over, the HR called me and said that I did well in the technical interview. They asked me for an HR interview through video conference. I insisted and agreed to an in-person interview rather than a video conference. However, I was unable to get tickets, so I called back and said I would opt for a video conference. The HR said they would call back, but as of now, they are unresponsive. I am afraid that I have been rejected. Please suggest something.

Regards,
HP

Don't worry, I would just phone them again to follow up and agree on a date. Do not be afraid to call them once again; you are showing interest in their company and demonstrating that you pursue your objectives! Good luck!
