Yes - good insight. I have been wondering about this too. For my 15 years, I've only ever worked for software companies doing new product development. So, there's a disconnect when I'm talking to people who come from IT backgrounds. Developing new products requires different skills, and knowing intimate details of specific tools isn't as useful as knowing the full capabilities of what that tool can do. The worst part of my background, and for these types of interviews, is that I typically switch stacks every couple years. Generally, every time I start a project, I have to re-evaluate the stack. And, choosing one depends on so many variables. In the past I've spent spent probably 50+ months killing it on SQL Server, but sadly all those details have been wiped from my working memory, because I haven't touched it in 12 months. But, that doesn't mean I'm not effective. It just takes me a week to re-engage and get effective. But, there's never been a job where I didn't become one of the top performers in just a few weeks. My brain just works differently.
