Security was maybe 5 minutes and immigration was probably between 15 and 20 minutes iirc. To give you an idea, we landed at 11.15 at the furthest possible remote stand and were in bed by 12.45. It went like this: 10 minute wait in the aircraft, 15 minute bus ride, 10 min walk to security, 20 min to go through security and immigration, 5 minute wait for our Uber, 15 min Uber ride, 5 min check-in, 5 min walk to the room, 5 min to undress and brush teeth.
