The first interview was one on one with a S&T product controller. The controller was kind, welcoming and made sure to ask me about my day before we started. The questions were mostly behavioral with one or two technical questions. We went over my resume and I was asked about what I had done & learned in my previous internships/organizations I am in etc. The behavior questions were the run of the mill regular "Tell me about yourself", "Tell me about a time you had a problem with a team & how you fixed it", "Tell me about a time when you had to act as a leader". The technical questions were simple and could be answered if you have prepared beforehand and read up on current events. He asked me to explain some factors that could affect a commodity market, and the way I preferred to trade commodities (no math questions). I heard later that night that I made it to the second round and the following week I was flown up to HQ and met with several different employees before beginning 2 different interviews (back to back). The first interview was all behavioral questions. The second one was a mix between behavioral and technical. Know basic accounting and finance(be able to connect the financial statements) and current events. They won't question you with mental math or hard investment banking questions. Know your resume well, they will ask you in depth about it. After finishing my interviews, they asked me to rate their interviews. They proceeded to give me a prepaid card loaded with what they expected I would spend while in Wichita (It was plenty) Also, they offered all interviewees a tour provided by an outside service (who is absolutely hilarious and makes wichita sorta not boring). Overall a great experience!
