well, you are right. I built up and worked only for one company. Why exactly do I need a bigger sample size in order to  write down how I recruit, how and what I learned about interviews and what has worked for me and what has not? I am not stating that I have a solution for every situation or every company on the planet. Take it as what it is meant to be: a possibility to reflect your own interviewing behaviour and perhaps taking one or two new ideas with you :-)
