A friend of mine wrote a good post on hiring the right people over at his blog:
If you sit down for an interview and you, as the employer or hiring manager, have all the leverage, you are hiring the wrong people.When you only attract candidates who need a job, who are focused on saying what you want to hear, who have become professionals at interviewing, you have all the leverage. You are not trying to woo them, they are trying to woo you. You control the selection process, dominate salary negotiations and dictate start dates, job descriptions and other details. You have all the leverage. You are in total control.
It’s a good read. Take a few minutes, especially if you’re involved in interviewing and hiring, and take a look!
