I look to hire people who just need a job. People who are qualified, but not overly qualified. People I know will depend on the job for a long time, but not looking to make it their lives. Hard workers - getting there on time, but also leaving at the stroke of 5. Ivy league schools are a red flag. Huge resumes are a red flag. These people will constantly question whether every decision is optimal, prod incessantly at company strategy, continuously try to impress, and are always hungry for praise, recognition, and "interesting work." When they get bored after 6 months, they quit and go somewhere else (remember they can easily do so because of their pedigrees), often to a competitor, bringing company secrets with them.
I need someone loyal, who knows how to take orders without question, and is prepared to do the work that needs to be done day in and day out because they want the paycheck. Reading the above, you might think I'm a terribly demanding boss, but using this hiring strategy has produced a 100% employee retention rate and by all accounts we are all quite happy.
