There is always a lot of discussion about recycling previous PNQ's if you passed the written test in an earlier iteration. I guess I fall into the camp that if they are your very best stories that specifically answer the questions, then you should use them again. I am going to practice what I preach. However, this time around we have six questions to answer, and the sixth question is more like a mini-SOI than a PNQ per se.
The PNQ's tend to be pretty static, but one of them was worded a bit differently so I will tweak that PNQ to answer the specific tweak in the question. I have great stories that address leadership, management, and cross-cultural compatibility so there is no reason to mess with them, and I am changing one PNQ to add a newer experience. I think the mini-SOI will be the hardest to write because there are a lot of questions to address in 1300 characters. This was a really good addition to the PNQ phase IMO.
It seems as if the bar has been raised and fewer applicants are getting through the QEP phase which is why I am sticking with my very best stories. I am on the record and we'll see what happens.
