I spent so long preparing for this lightning-fast phone interview that felt rushed and incomplete. The interviewer kept on stating how he has a large number of interviews, and he needs to get through this one as fast as possible. Sometimes he cut me off while I was trying to describe my background, or even answer the more technical questions. He also continually described how stressful, demanding, and miserable this position would become. I would "miss a lot of sleep, work weekends, work holidays including Christmas," and made it sound like work/life balance was a disaster. After the interview, I heard nothing, ever. I thought it went well despite the fact I didn't want to work there after the interview, which is why I never followed up. I would have liked to receive some kind of feedback, however. I was receiving other offers at the time that paid much better and generally sounded much more positive. I don't want to work for GD now, even though I have a friend who does.
