Doha airport does not meet international standards.

After your Qatar Airways plane has landed, you can expect the following : a 15-20 minute scenic bus ride to arrive at the airport building, expect to wait 30 to 60 minutes to pass passport control, wait for the scan of your handluggage, pick up your luggage, then wait 15-20 minutes for a taxi.

When you leave Doha you can expect the following : check-in time is 20 minutes, wait 20-30 minutes for the passport control in area that is too small and noisy, enter the departure hall, try to find a seat, people are sleeping on the floor, not enough toilets and the one that you will find will be very dirty, wait for the bus, 15-20 bus ride to your plane.

Enjoy the experience.
