I applied through campus recruiting and received an email letting me know I had an interview on campus in the coming week. The first round interview was held at the campus career center. I met with one of the managing directors and had a 30 minute interview that was pretty informal. The questions were mostly behavior, but there were one or two analytical ones.
For the AC
1) group round - did a case study and each of us were asked questions based on our group answer after
2) math and verbal reasoning test, written essay test
3) individual interviews - one with current analysts about cv, one with a partner (casing)
Pretty basic behavioral questions - no technicals. I'd recommend knowing your "why" and being able to clearly explain your interest in the specific practice. Also, prepare to ask the interviewer more in-depth questions, too.
Online assessment including verbal and numerical parts for the financial and economic consulting intern position. Given one minute for each question, I insist the time was quite tight for verbal part
