Moving to Doha, need to access job offer

Hello I have an Job offer in Doha, and need your advise

How much does a 2 br apartment cost in Doha and are they readily available I was told that the following neighborhoods are good middle class areas ( Mansoura, Al Sadd, Madinat Khalifa – Jamal area and West Bay Heights ).

The employer doesn't give any private medical insurance and he assured me that the government/public hospitals are very good, with excellent qualified doctors and that they are very cheap for expats.

Do most companies work 5 days a week or 6

If for what ever reason things don't work out as planned do employers put a ban on the person.

I have been in Dubai since Protected content have only visited Doha in Protected content a day so I am sure things changed a lot and would like some actual feedback

Best Regards
