Applied through OCR followed by on-campus 1st and 2nd round interviews then a superday in NY. 1st and 2nd round interviews were with 1-on-1 with an associate then a VP. Super day format was multiple 1-on-1 interviews as well as a group interview. Overall, process was rather simple and the interviews involved the standard investment banking interview questions (walk me through your resume, DCF, WACC, basic accretion/dilution mechanics etc)
