Although i haven't heard of a call centre in Doha but can surely give you an idea of what you may end up paying as rent for accommodation. You'll likely pay QR2500 to QR3500 as rent for 1 room with separate bathroom and kitchen in a villa. If you prefer an apartment in 1BHK or 2BHK configuration, you'd be paying close to QR4500 to QR9000 depending on location. Dafna, Westbay, Al Hilal, Madinat Khalifa are areas with many many villas and apartments that you may rent based on your living standards and spending strength.
