This is an off-shoot of the earlier topic on giving a design exercise
in an interview. Several people mentioned making this as realistic as
possible; for example, if the design process is collaborative on the
hiring team, it should be collaborative during the interview.
That makes sense, but I'm not sure how to go about it. (Maybe this is
why Jared said it is hard to do this effectively.) Let's say that I am
interviewing the candidate. It might be hard for me to be a
collaborator on the design exercise since I'm trying to evaluate the
candidate. So I could pull in one of the designers on another team to
be the "collaborator." What should their role be? They need to sit
back enough to allow the candidate to shine, but they need to be
involved enough that it feels collaborative.
Also, would you use the same collaborator for each interview? I'm
wondering whether it would be difficult for the same person to
participate in the design exercise multiple times and appear that they
are genuinely interested in solving whatever the problem is.
