The best organizations are always seeking the best talent. They realize to grow they will need to have good people. They also know they will need to replace people that may leave, and they may also need to upgrade or exchange people from time to time.
It is said you can loose with the best talent, but it is hard to win without it.
Therefore the best organizations are always fishing for talent. They always have a bait in the pool hoping to attract a bite.
They don't wait for someone to apply, they are fishing for people they want to hire.
It is rare to be able to find someone outstanding on short notice, so having a pool of potential talent is always a plus.
Always be fishing. Always be fishing for the best availiable.
