Inside the Vault presents Terry Dunn, quality assurance tester.
What’s your job at Bethesda?
I am a quality assurance tester, which basically means I get to play games for a living. While it may sound like a glorified position to some, it actually requires persistence, conviction, and thoroughness. It’s my job to track down issues in our games, find a way to reproduce it if possible, and then write a report up for it and submit it to the developers for review. When fixes come in, I double check it to make sure the problem has been resolved.
