Boeing Structural and Payload Design Engineer I interview questions

I interviewed with boeing on a tuesday on August 8. It was a structured interview with 4-5 questions. The thing was that they interviewed me for a position that was never posted on the job list, the position was never posted online and yet i was interviewed for it. I hope this means i have better chances but i dont know. I orginally applied for a structural design engineer position but i guess i got interviewed for a different req#. I think the interview went well, i explained all the answers and had alot of examples. I had a large portfolio of projects that i have worked on even in the aerospace industry. Im not sure when they will get back to me. Im wondering if anyone knows how many people they interview per position.
