Is the exam exclusively on paper or is there a verbal option? Paper exams can be stressful for anyone, so if you find that explaining things to a person much easier, perhaps you can ask for an accommodation to take the exam with a proctor verbally rather than written. Good luck!

I second this view. If the interviewer maintains a critical approach to their analysis of the interviewees responses, I see no reason to discontinue watching. However, having a guest who is consistently an unreliable source of information and taking their views at face value screams red flags to me.

Kind of like assessing a new relationship, if your prospective partner becomes someone completely different around friends with opposing views, run. They aren’t an objective source, they are a mirror with a megaphone.
