Recruitment department is full on BUSY, trust me, when you walk into training college and see all that is happening you begin to realize the big task that they have to do on a daily basis to keep the place moving from ab initios to recurrent to upgrades etc ... Keep in mind also They have no obligations to hire on the spot who ever made it through FI , its a business, as soon as the need for crew comes they start the process of calling who ever is on the waiting game pool (i.e. people waiting for GC) and on top of that you accommodation issues, where they must plan who goes where and more importantly , do they have enough buildings to put the new joiners ! Think of it as a big movie production where the end product is you graduating from training !
To add to speculation, August is going to be a slow month because its Ramadan and office work tends to be on the very very slow side
Good luck
