Back in 1997, I had an interview with 3Dfx and Nvidia.
The 3Dfx interview lasted a short hour as the QA manager had more tats and body piercings than I could count, and the company was doomed as his boss was the marketing manager. If you ever read Dilbert, an engineering company run by the marketing department is always doomed. 3Dfx peaked in 1997 and declined into bankruptcy over the next few years.
The Nvidia interview lasted eight hours, as various members of the QA team came in to quiz my knowledge of video cards, PC hardware and software testing. I almost got the job. Not surprisingly, someone else had that little special something that the hiring manger was looking for. Of course, Nvidia is still going strong.
