In my experience, most of us seem to decide on the operator of our choice and then bust our pooper to get hired. We go in there with somewhat rosy coloured glasses and full of hope that all of our aspirations will be fulfilled.
Then after the rose tint has worn off, we realise that this operator is not neccessarily better or worse than the other one. Our aspirations, whilst admirable were somewhat unrealistic and not all of them can be met.
So, we start looking for greener pastures, we talk to mates who give us glowing reports of their super employer and we decide, this is the one for us. And the cycle starts all over again.
The reality is that it's only the depth of the do-doos that varies, not whether it exists.
