You know, an interview not only gives the prospective employer to get to know you, but it also gives the employee a chance to see if they want to be employed there.
I don't work for Qatar, but it would certainly perk my ears up if they asked me to put in an 18hr duty day on my interview. You should consider yourself lucky of experiencing such frivolous regard for rest and duty times before making a life change like joining a new company and moving your family to the sand pit.
Just my 2 cents.
