now I know what CIA interrogation feels like. It makes you sweat, and cause you to doubt your answer.

3 different interviewers ask me same questions again to determine if I answer the right question. Interview lasted 3hrs. I can't recall the questions since I was thirsty after 20min into the interview. I drank alot of water.

they deliberately put me in seat under bright light while the interviewer sat in darker area of the room. The light shined in my face causing glare.

This technique sounds like CIA interrogation to me.
