I applied through college or university. I interviewed at FTI Consulting
Interview
On campus first (and only) round interview with two senior members of the firm. The interview was almost exclusively behavioral. The questions were designed to gauge analytical skills and thinking. Offer was extended shortly after the on-campus interview and sufficient time was provided to respond.
Interview questions [1]
Question 1
Take a technical concept that you understand and explain it to me as if I did not know it at all
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
