How to ask questions in correspondence?

Question

linux

Interview through correspondence.
How to ask questions correctly to be sure that the person answered himself, and not googled?
I.e. if a person understands the subject of the question, then he will answer. And if he doesn’t know, then so that he can’t google for a reasonable time.
Can you give examples (network administration, linux development, C)

Answer 1

Ask him practical tasks to check the logic of understanding the processes and the technical component, for which you can’t google the answer in 5 minutes :) for example, how to organize a network of so many PCs, examples of tasks in C, that is, to understand what the general level of a specialist is.

Answer 2

If a person can quickly google a question, then he is no longer a bad specialist.

Answer 3

I think it's practically impossible. I (like many others) have a question: why not on Skype?

Answer 4

Hmm...never encountered. Not on this side, not on this side. Put the question in such a way that the answer to it cannot be googled in a reasonable time. Well, again - if a person can google the answer to your question, then he at least knows what and where to look for.
