Partners in Health interview questions

Extremely tedious- 3 rounds of interview without assessment round, so 4 rounds of interviews in total. The entire process took about 2 months with series of communication with hiring manager. I would say my experience was negative because it took a week or 2 to get any response from the hiring manager about whether or not I was going on to the next round of interviews. Also, I did not hear from the hiring manager after been told that I would receive a call from them to inform me of their hiring decision. I later received one of those generic disqualification emails. They wasted my time.
