Leave policy for remote role

Hey I have worked in 2 startups in my careers, In both places leave policies aren't that great. Just wanted to know what are policies in other workplaces

I am interviewing with an early stage startup in Gurgaon. As part of their leave policy, they offer only annual leaves which you earn at a certain rate every month. They do not offer any sick leaves or casual leaves to employees. Is that even legal? Have you heard of similar policies elsewhere?

I was raised abroad and I always thought there’s something called annual leaves where you take PTO for a month apart from your sick / casual leaves. However I started working in India and damn when TF do people have time to do things apart from coming to office and getting burnt out?

What is the reality of these unlimited pto/leave policy that companies have, I'm unaware as i am a fresher. Also which companies offer remote roles and unlimited leaves/PTO in india? do comment if you know or are in one!

We have been given unlimited leaves subjected to approval by our managers and that our work is not affected. Since there are no leaves, it can not be encashed at the end of the year. I wanted to check in with you and ask how many leaves do you all get?
