How is Zenoti to work for? How good are the compensation and hikes there for a Sr.product/product operations manager?

I just had an interview with Zenoti for Lead Ai Engineer role and Interviewer was horrible, he said to expect at least 12 hrs work everyday and weekend working. This is still fine what he did is really horrible and I'm not sure how an interviewer can do this. Right after the interview he contacted my current company senior manager and told him that I interviewed at their company. I just got confronted by my current company senior manager. This interviewer's name is Hari Krishna Malladi. Beware, he might be doing this to all interviewees. It is ethically wrong. Imagine the impact it has on my current role because of him. I did not expect a senior person to behave so unethically.

Anyone any idea?
