I work as a software developer, and on the interview panel for new hires in our area. I've become very picky with respect assessing both technical ability and fit for the team. I've learned that challenges of working with people who not a good fit.
I'm living back home on my father's farm when he is going through some medical issues. We've had some timber/pallets/construction equipment stolen recently, and it's made me very wary of people who arrive here (we have a lot of people due to some temp help, regular diary farm activities and some maintenance projects). I'm inclined to speak to the people, note the make and model of vehicle and so on. In fact I keep a log of visitors, and now have camera system in the main yard.
