Qatar Airways,, 1500+ pilots and 5700+ Cabin Crew, 10,000+ ground staff. Do you logically think this block of flats are for the lesser number ?
One would think that it would might be available for either Flight deck or Cabin Crew, but lets not forget Office staff, Al Maha staff, Premium terminal female staff of which there are nearly 700, the list goes on.
I personally would not jump to the conclusion that this is for Flight Deck, the CEO's favorite employees
