Shadow interviewers don't do a separate interview. They typically observe an interview done by an experienced interviewer and then write up feedback. It is primarily meant to be a learning experience for the shadow interviewer. They will get to see the feedback written by the primary interviewer, and the primary interviewer will usually critique the feedback from the shadow interviewer. The feedback from the shadow interviewer isn't actually dis-carded - it gets sent to the hiring committee, with the indication that it is from a shadow interviewer. It can be given less weight by the hiring committee members, but I've been on hiring committees where the shadow interviewer picked up on something that the primary interviewer missed that affected the hiring decision.
