I couldn't help but read this and think about technical interviews that involve the candidate being asked to write code on a whiteboard - no Google, no code linting/hinting/completion etc.

I'm very much in favor of candidates being asked to write some code under more realistic conditions, including finding solutions to parts of the exercise online. Of course, they should then be able to explain to the interviewer(s) why they chose a particular solution and walk the interviewer through the code they borrowed/adapted.
