We're interviewing to replace a current manager. After the meet and greet part I start by asking the interviewee to answer the following behavioral type questions with real world examples from their past. Tell me about a time when ... type questions. They nod as if they understand. They then proceed to say "I would do this, I could do that". I'm sorry. I'm asking how you handled a poor performance employee. Don't tell me you "would" talk to them about it first. Tell me what you ACTUALLY DID. I can only conclude that you've never been in this situation (unlikely) or totally botched it when you did and don't want to tell me. When I press again to give me a real example they continue with their would of should of story. Ug. So, none of the 3 so far will be getting the job!
The moral of the story is to come prepared to the interview and to answer the question with your own real world experiences. Is that so hard? Apparently so.
