If all the rumors are true it will all translate into a very bad start for the relationship between QR and the new pilots. New joiners may take any accommodation they are given as they need the job, but as soon as things improve they will leave. The honeymoon will be over even before the marriage is consummated.
If Qatar Airways wants to keep these pilots for a long time they must find a solution to the housing problem as soon as possible, of course most probably they don't.
