What are the common ways that interviewers evaluate your skills?

If you were being interviewed by a large organization or company that is seeking a web editor to update their intranet, what are several ways that they would evaluate your skills during the interview? This is after they’ve reviewed your portfolio and selected you for an interview.

  1. What questions do they ask about your web coding and programming abilities?

  2. What questions would they ask in general, just to see how much you knew about web design principles?

  3. Were you given a test to complete in front of them?

Thank you for your advice!
