Just look for friendly people that like being around people. When you can feel the energy the moment you walk in the office you have the right team. I have walked in to many offices for a property tour and the staff will just ignore everyone, makes me wonder why they are even at work. One bad apple can bring the whole team down, it is amazing what can happen when you remove the person with the bad attitude.
