when my husband had an offer from QP, as soon as the test is done (basically just make sure you that your hubby fit to work and don't have any critical illness) the agent who look after u from your country will sent the report to QP. I think it was about 1 month for us from the interview in London till we board the plane to Doha.

But with Ramadhan coming soon, you will have to expect things will go slower because they will have shorter working hours.

Good luck with the new job.
