Summary: during technical zoom-based interview I looked around while thinking for answer. My interviewer commented that maybe I am looking for answer online. I showed them that there is nobody else in the room. I passed the exam but feel like I've been accused of cheating and don't want to work for the company enymore.
I was accused of cheating during a technical video interview in a well-known company. When the interviewer asked me questions, I was taking a moment to think, and looking up and down to think, and not directly facing the camera. This happened for 2-3 questions. I usually look up or down and talk to myself when I am trying to think about the answers.
The interviewer told me, I don't know why you're looking up/down and sideways, and I am not sure if you're looking at answers on the Internet, materials, notes, etc. I composed myself and turned around my camera to show him there's nothing in front/back/sides of my laptop and told him this is my thinking process when I usually think about a problem at hand.
Later, I received an email from the HR that I passed the interview, and that they liked my skills and would like to interview for the next round. I am kind of bummed out that the interviewer accused me of cheating. Should I go/not go-ahead with the next interview? How do I decline and pass the message to the HR that I am not interested in proceeding forward?
