Hi,
Get the address of the company.
But one thing is it is very hard to find the companies in Kinshasa.
Things are expensive in India and the country is not so comfortable for people who doesn't have French knowledge.
But French is not really hard to learn.
Find out the salary what they r paying.
If the salary is more than USD 2000 and if the company takes all the expenses including the food, cook, maid transport and accommodation then it is worth.
But Kinshasa is a nice place and can find lots of indian citizens living nearby.
If you have further queries u can skype me on ganeshkv1.
Regards,
Ganesh Kumar. V
