I applied through university. I interviewed at Castleton Commodities International
Interview
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.
