Offer review from E-commerce startup

Recently interviewed by a growing E-commerce startup (valuation > $10 million) for an SDE-2 role and then got the offer. YOE- 3.5 years.

Current salary-

1. 29.8L base + 2.2 Variable
2. ESOPS worth 20L vested over 4 years
3. Company- Fintech

Offer details:

1. 36L base salary
2. ESOPS worth 20L vested over 4 years
3. 1L bonus after 3 months of service.

But there is a catch:

1. It's 6 days WFO.
2. The founder himself told me that the normal working hours are 12 hours a day at least, and 1 out of 3 new hires leave the company due to work pressure.
3. Extended offer only after 1 round of tech interview, normal companies take 2-3 rounds.

I am in a huge dilemma, this is a dream salary for me, but the above points are scaring me. What should I do, please help folks?
