It was based around the STARS concept as well as personality and experience based type questions. The interview started off with describing my background and my current experience. I was then informed of the job, its roles and responsibilities. Then I was led into a questionnaire asked by 3 different people on 3 different topics: technical, personality, and behavioral. It was very professional and they offered me the opportunity to ask questions, as well. It afforded me the opportunity to be sure this was a job that I was truly interested in and see if my skills matched what they were looking for in their potential candidate.
