So the study seeks to investigate the role of an in person judge on the whiteboard interview. The study found that a private whiteboard interview, where the candidate gets the same problem but solves it without a judge in the room, was better at evaluating software engineering skill than the same question with a judge in the room. To your point, we can keep all the benefits of algorithm questions with less of the disadvantages by modifying the typical whiteboard interview to just remove the judge in the room.
