Everywhere I have been, there has been no shortage of people looking out for a job. Every single place, every single time, there are reasons a plenty to look out. Either the money's not good, or the job's not good, bad bosses, different location preferences, boredom, girlfriend in another town, homesickness, restricted growth, function shifts, graveyard shifts, Saturday working, etc etc
All said and done, no one is ever happy. Except when your nearing gratuity (4.8 months to be eligible) you manage to trudge along, and then its run run run.
There are a million sites, which give you tips on job interviews. Dress well, polish shoes, perm your hair, Acceptable Jewel standards, Smile, carry near folder, etc etc. There is also the free advice you get from your everyone, don't jump companies, liquor is a bad place, service industry is a tough place to move from, shouldn't negotiate too hard on salary, etc etc.
All said and done, there is only one truth at the start. Getting to the table. Once your at the interview table, its all in your hands.
