Appinventiv Business Analyst interview questions

The interview process was fine. They asked basic questions in both rounds. The main issue is their HR process and ethics. Before the interview, I shared my current and expected CTC. The HR informed me that I am selected and will send me the Appointment Letter in a day. After this the HR was non-responsive. I called HR numerous times and in the end, she informed me that my status is on hold because of the Salary Bracket. I wonder they knew my expectation before the interview and selecting me, then how come this role is on hold in a day. I checked the same with my friends and they faced similar issues.

Worst experience ever I had...they rescheduled my interview for 3rd time in a single day. Every time I joined the interview meeting there was no interviewer. Ever HR didn't pick the call. You will not get any prior intimation for interview reschedule.
