Reached out by phone call and make the appointment, but suddenly change the date, so need double confirm with them before have interview. Interview with HR team around 20- 30 mins Basic question like introduction and why change the job And introduce current job and what did i do now,

I have been referred by internal employe and shortlisted for the interview process, there were 3 rounds of interview reverse the ladder. First round was with the Snr Manger from the Headquarters, 2nd with local Snr manager and last was with Operational manager. I cleared all the rounds with positive feedback but its been 2 months since I received the feedback from any of the HR team. Even after regular follow ups they just left it in the middle of the ocean.
