BMO Financial Group Software Developer interview questions

A headhunter sought me for this role. I was not given a role description in spite of asking for one. Just that there was a requirement for a SAS developer. In the interview , the interviewer seemed to be only concerned about whether I had experience with SAS DI Studio. That was the very first question and I said 'Never'. At this point, he ran out of questions I think. The next few questions all centered around DI Studio. "Have you done this with DI Studio? Have you done that with DI Studio?" You must be kidding me. What was my answer to your first question? Anyway, it felt like the interviewer had very little knowledge about SAS's core programming component and wasn't equipped to ask any competent, analytical questions. There was 0 importance given to understanding my experience, skills or thought process. It was disappointing to say the least. I left the interview mentally about 5 minutes in. After that, it was just an uncomfortable wait to the end. It also left me with a slightly bad impression about the company.
