And also on the Bethesda Blog you can find their last Inside the Vault featuring lead interface programmer Erik Deitrick:
What’s your job at Bethesda?
I’m an interface programmer. So I work on menus and minigames.What other games have you worked on?
I started off at Ubisoft working on Tarzan Untamed for the GameCube, which was a platformer geared to a young audience. I then worked at a failed dot-com making small games for a platform that never made it to market, which is a shame because my head-to-head wackamole would have revolutionized all mole-based games. Then I got hired here at Bethesda and worked on Oblivion, and now Fallout 3.
