For some reason I do not fully understand, the people who pester me the hardest for jobs tend to work out the worst as employees. I cannot think of a reason this should be true, so perhaps this is just an artifact of having only a few data points. But yet again we recently had another person we had to terminate who pursued me literally for years for a job, only to be unproductive and ineffective in the job from day one. For some reason energy and enthusiasm in the job hunt do not translate to energy and enthusiasm in the job.
I have come to think of these as Obama employees -- people who are brilliant and energetic in seeking a job, but ineffective and oddly unmotivated once they have the job.
Postscript: Last year, we had about 300 seasonal employees. Of these, perhaps 50-75 will choose not to return or will not be asked to return the following year, opening up that many positions for new hires. For these 50-75 spots, we had over 22,000 applications last year. And since many of these applications are for a couple, we really had well over 30,000 applications. This makes us more selective than Harvard, lol.
