Halifax Water interview questions

It was a technical and behavioural interview. They asked me nine questions, all related to database management and data security. After these nine questions, they asked if you had any questions you could ask.

Interview was with 5 different people all at once. Each interviewer had their own set of questions, with many repetitions. Questions were extraordinarily generic, showing that no understanding of your resume/cv was given before the interview. Questions were asked in a list form, with no personal or contextual questions given. I was also left alone in the interview room for some time, which was also quite cold (15 degrees) while waiting for people to show up. Additionally, you're asked to complete a personality and IQ test from The Predictive Index before the interview. These tests are known to be highly irrelevant and unreliable.
