Hi Amaghrebi, Thanks for your feedback.

I've made some calculations and I would need 5,5k to 6k for furnished 1 room apt or Studio, 3k for myself and 1,5k for the car (I will take a used car..) this gives an average of 11k to 12k per month for a descent life which leaves me 4K (1000 USD) for savings and extra-expenses if any.

Do you confirm this? or maybe I am under / over estimating the number?

Not sure if its a good offer for a senior position in a big 4.

For the question related to leaving this office, there's an anti-concurrence clause that prevents me to join another big professional services firm (but I m used to this and it is the same thing in Tunisia) but nothing is specified if I want to join a company as back-office or manager. The restriction only applies to other concurrent consulting firms.
