What are good questions to ask to a service designer to evaluate his skills during a job interview?




My two cents

The same question you would ask in any other job interview work perfectly well when hiring a service designer.  To me, the best way to evaluate skills can be done with some of these technics:
  1. Go in depth about a project in the portfolio: Ask the person to describe details about on the tiny part of the process or tools she used.
  2. Propose challenges: For example, take a real challenge you had at work and that you have fixed already and give that challenge to the person in the interview. Ask her how she would fix that problem. Another example of a challenge could be to ask the person to make a "time" budget for a service design project. Here the service designer has to create a plan for a project and estimate how much time he'll use for each part. Then give the same challenge but with half of the time, and see how the person deals with constraints.
