Need advice

Got placed at LnT Infotech through my college placements
Free-lanced at a company for four months and got a job offer from them with the same salary. But the work load is too much. There is no such thing as personal time. It's work 24*7. However, the exposure is good. For one of the projects I was the PM. Had dinner good exposure. But as I said, to much work. I lost quite some weight in the one month that I was the PM.

So now the problem is, should I join an MNC where my exposure will be terrible or a start-up where my personal life will be terrible
