A phone interview and then they flew me in for a presentation and a series of eight 1-on-1s.

In this series of 1:1s, lots of questions come over and over and make it boring. In addition, every interviewer tends to ask questions about his own background, and that may have nothing to do either with your background or with the job you are applying for. Since it is an interview, you do your best; the good thing is that these questions in general are not difficult. I thought I aced the interview; they promised they will call the next week, but never did. Two weeks after the usual thank you, I sent a follow-up, but nobody replied (HR or hiring manager), and after more than two months, they sent me a rejection notice when I had already forgotten about them.

How to detect a flaw in a large image containing repetitive features?
