Of course, this should also go the other way. As an interviewee, your task is both to prove yourself and to make the interviewers prove that their company is somewhere you want to work. So, ask probing questions about their culture, their code, their processes, their structure, the foundations of their business. And if they don't give good answers, or get upset about the questions, run away.
Absolutely. And I would say the same thing to interviewers: Part of the dynamic is of a candidate being skeptical that the company and the job are as good as they sound, and asking you to prove it. If that rankles an interviewer, seeking candidates through networking where the candidate arrives with a certain realistic view of the prospects is also a good thing.
