Hi All,
I try to give some explanations about Kinshasa
DRC is a big country. They have manys cultures and languages (I dont remember haw many it is. You can check it in Wikipedia). But, as conversation, they use French (national language), Lingala and Swahili.
Most of Congoleese like to have a drink. So, if you're drinker, you can find beer easily here. They also have the local one, Primus. They love to dance. You're gonna find a lot night club around the town. But, you must be careful. Choose the good one.
Most of community are Christians. However, if you're Muslim, you still can find mosque around the city.
The environment is not really good if you're living in the down town. There are a lot of 'Seghei' (street boys) that can disturb anytime. They asked for money, and it's not seldom happened they force people to get money. So, be careful with them.
Living cost is totally expensive, especially if you're living in Gombe (one of subdistrict in Kinsasa where the most expatriate live in). As comparison, I stay in apartment with 1 bed room, 1 living room, 1 kitchen and 1 bathroom. It cost me 850 USD / month. The apartment is not too god, but not bad at all. If you want to lie on the sub urban or rural, maybe you can get the cheaper one.
Electricity and water are the common problem that you'll face very often if you stay in DRC. So, prepare yourself for it.
Job opportunity? I don't think it's much. Make sure, you already get the job when you come here. Don't gamble with it.
cheers,
nurul
