Arm Support Manager interview questions

Interview Process continued for approx 2.5 Months, which included 3 technical and 1 HR round and later I was asked to provide my latest salary documents as well so that HR can work on salary offer, this means I had cleared all interviews and its just matter of sending me an offer letter, based on the feedback from a Senior HR. But suddenly he stopped responding to my emails and calls/messages. HR's in Bangalore are highly irresponsible that they dont even have guts to say NO to the candidate if the dont want to peruse with the candidate, when he/she is chasing them for a feedback. Poorly managed interview process and lethargic HR's
