3,442 database administrator interview questions shared by candidates

The most difficult questions were the live HireVue questions. After being able to practice on generic interview questions they turn 180 degrees to technical questions which in itself is enough to make one take a step back. In addition the questions were not in line with the job description. The questions were 1) what is a @page directive 2) difference between delete and truncate 3) difference between clustered and non-clustered index.
