I'm waiting for the world to catch up with the fact that looking up information while you are working is a core part of any real job. Do I care if my Linux Security Professional spends a few minutes looking up information on the internet before taking some action? It's not the case that anyone can solve any problem so long as they have a search engine. Without domain knowledge, an open ended web search is not going to lead to a convincing answer except for the most trivial questions.
This extends to coding interviews as well. Using the resources at one's disposal to get a sense of the landscape before diving into algorithms must surely be part of the job, right? What do I care if a developer needs a quick reminder before diving into a solution, or even reads up a bit and scans someone else's code before answering?
What is the value in ensuring that people have perfect recall if this is something that will almost never be necessary in a real world job?
