I once had a job interview. The interviewer gave me some graphs to interpret. While doing the task, I found a mistake in one of them. I tried to show the interviewer how to correct the graph. He got irritated and said I wasn’t a suitable candidate for the job. Two weeks later, however, he called me, apologising and explaining that the company workers hadn’t noticed the mistake. He offered me the job and an attractive salary. So if you feel sure you’re right, learn from my lesson and don’t be afraid to say what you think at a job interview. It might pay off!
