bp BP IST interview questions

Came to my university after I applied through my university and on BP's website. I applied to only the Trading Internship, but ending up interviewing for a completely different job. I didn't find out until the interview. I was completely caught off guard and honestly mad. I would never work for a company that surprises you like that and thinks they know your interests better than yourself. Anyway, I ended up interviewing for a finance position within IST, that I was uninterested in and would never accept. Interview started off behavioral based then moved to an easy case study. After the case study, I had many questions about the position and the interviewer didn't know a single answer. It was laughable. A complete waste of time.
