I once interviewed an internal candidate who failed my interview miserably. I am not a manager, I am an engineer. In the coming months, whenever I saw her walk by me in the hallways, she would put her head down or not look at me. A few months later, I learned that she had quit. I felt quite bad about this although it was not my fault really.
