Castleton Commodities International interview questions

First step is online test with questions on Math and programming including but not limited to Python, SQL, Regex. I got first round interview through OCR. First round interview was mainly behavioral (why commodity? etc.). However I heard that some people got technical so definitely be prepared. If you pass first round you get a superday with 5 back-to-back interviews with a case study that you have 24 hours to prepare beforehand.

Took over one month. Had over 5 interviews. The interviewers are respectful and intelligent. The only issue is that it seemed like there was no structure to the interview whatsoever. All 5 interviews had the typical structure of getting to know each other for 15 min, and then you asking the questions to the interviewer.
