Seema, should be around 15-18k/month. That should be just about enough for a family of 3. Anything below 13k and they're probably trying to underpay you. Be careful and don't give in too easily during negotiations.

Perks come with 48 days annual leave (including family care leave), 2 year hospitalization leave (only 16 months is paid leave), 3 years maternity leave, etc. You should re-confirm these numbers with the HR department before signing the contract.

Good luck!
