Tazzie, best knowledge, here it is...

1. Depending on your need (not experience!) How much do you need? Want?

2. Yes, stressful. Be prepared. Overtime, always.

3. Housing accommodation, better take the real accommodation because prices here just keep on going up high above. So you wont have headaches.

4. Nope. But I heard they have (like many other companies here) bonuses and stuff, especially airtickets!
