What do you mean by "something"? I am in France and if an candidate does not ask me "something" at all it is usually a big red flag.
To see some code is definitely out of the question, though. But asking about the development process et all I find to be the type of mandatory questions I would ask as a candidate (and expect to be asked as an interviewer) even if I already knew the answer, just because not doing it would be strange.
