The questions in this guide have been selected using this framework: (1) Questions should reflect understanding of concepts (2) Questions should reflect actual handson experience (3) Questions should not be based on memorization of arcane names or syntax (4) Questions should reflect issues seen by the majority of DBAs of that skill level. The intent of the questions is that most DBAs, for a given skill level, can successfully answer most of the interview questions. Naturally, no one person could be expected to flawlessly answer all of the seniorlevel questions. Even the most adept DBAs have some areas of weakness. In order to test the fairness of the questions, I asked numerous DBAs, from different backgrounds and companies, to review the questions.
