Random, unrelated to the job. The interviewers hadn't read my CV. There were 2 interviewers, each asking questions one after another, without giving enough time to focus , nor to answer. The questions were not related to the Job description necessarily. It was one of the worst interviews of my life . My recommendation would be for them to have a structure for the interviews. Secondly, ask short relevant questions and allow full opportunity to the candidate to be able to provide the answer.
