I don't suck at interviewing, people who interview are usually as clueless as interviewee, so you can abuse this game from your side as well. I completely agree that people you hire most of the time have very little with what you need and want and that process is broken.

Suggestion in this post is how I would go about it as well, give people 2 weeks to try it out and see if we work for them as well as they work for us.
