I applied through college or university. The process took 2 days. I interviewed at FTI Consulting (Houston, TX) in Jan 2008
Interview
Had an initial interview on campus and then a superday at their office. On the superday, I interviewed with 4 different people at different hierarchical levels. Everyone was very nice. No accounting or technical questions. Mostly behavioral and fit.
Interview questions [1]
Question 1
Tell me about a time you had to make an ethical decision.
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
