CRISIL interview questions

Technical round 1 - Two people over telephonic interview, civil & qualified people who asked some good valuation questions. Good experience. Waited for 30 mins for the call , had to call them to remind that there was an interview scheduled. Technical round 2 - Relevant department head, Good technical interview. Had to wait 1 hour for the scheduled interview So this made CRISIL look good. But there comes HR who doesn't care a squat about the candidate. Zero respect. Had to call 10 times for every backup. Waited for almost a week to get the reply out of them. Worst response and professionalism. All technical interviews were cleared. Had final director round and finally after a week, they reply that job position had been filled. Poor interview mechanism and culture.
