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.
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)
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
